Alphabetical Command Reference

$iter (num index)
See User Manual > Miscellaneous Concepts > SQL Queries
Description
See Miscellaneous Concepts > SQL Queries for more information.
Example
a <no parentheses>
Description
This command is used to reference objects during iterations of certain flexscript commands such as forobjectlayerunder() and forobjecttreeunder(). This command does not require parentheses, and can only be used in C++.
Example
See forobjecttreeunder().
acos (num ratio)
Deprecated, use Math.acos()
Description
This command is deprecated. Use Math.acos() instead.

 Gets the arccos of an angle in radians.
Example
activateview (obj viewnode)
Description
For developer use. This command makes a GUI window active and visible. It should be used to open a window that is stored in the view tree without creating a copy of the view in the active tree, in order to make direct changes that will be saved in the view tree instead of being deleted when the window is closed. Generally, the command createview() should be used to open GUI windows. Use makeactive() if you want to make an already open view the active, or top, window.
Example
activateview(views.find("standardviews/other/FindReplace"));

 This opens the node called FindReplace in the folder called standardviews/other in the view tree.
activedocumentnode ()
Gets the currently active document window
Description
Returns the currently active document window. If the active document window is a tabbed window, it will return the active tab page node.
Example
treenode activedoc = activedocumentnode();
activedocumentview ()
Gets the currently active document window as an HWND
Description
Returns the currently active document window as an HWND. To get the node associated with the window, use activedocumentnode().
Example
treenode activedoc = nodefromwindow(activedocumentview());
activeview ()
Gets the currently active window as an HWND
Description
Returns the currently active window as an HWND. To get the node associated with the window, use nodefromwindow()
Example
treenode viewnode = nodefromwindow(activeview());
add (num value1, num value2)
Deprecated, use the + operator
Description
This command is deprecated. Use the + operator instead.

 Addition of value1 to value2. This returns the result of the arithmetic expression value1+value2.
Example
double sum = add(1,2);
addbundleentry (node datanode[, field1val, field2val, ...])
Adds a new entry to the bundle (base 0)
Description
Adds a new entry to the bundle (base 0). All fields must be added before adding entries. The optional field values will be added to the fields in the given order. Up to 29 field values can be given. For bundles with more fields, use setbundlevalue.
Example
int lastentry = addbundleentry(x, time(), current.subnodes.length);
addbundlefield (node datanode, str fieldname, num type[, num maxstrsize])
Adds a field to the bundle
Description
Adds a field to the bundle with the given field name. Returns the field rank (base 0) of the added field. All fields for a bundle must be added before any entries are added. The type is a bitwise flag that must be one of the following values:

BUNDLE_FIELD_TYPE_DOUBLE : stores a 64-bit double
BUNDLE_FIELD_TYPE_FLOAT : stores a 32-bit float
BUNDLE_FIELD_TYPE_INT : stores a 32-bit integer
BUNDLE_FIELD_TYPE_STR : stores a string. If used, you should also define the maximum string size, which will be the space allocated for each string entry. If maxstrsize is unspecified, the default will be 32 bytes. The field will be able to store strings at least as long as the specified length, and any longer strings will be truncated.
BUNDLE_FIELD_TYPE_VARCHAR: stores a string. This field type does not impose a limit on string length. This field type is recommended if you need variable string lengths, or if strings are frequently repeated.
BUNDLE_FIELD_TYPE_NODEREF : stores a reference to a node

You can optionally bitwise combine any of the above values with BUNDLE_FIELD_INDEX_MAP. All values in this type of field will be indexed for quick lookup (O(log n)) using getbundleindexentries().

You can optionally combine BUNDLE_FIELD_TYPE_INT, BUNDLE_FIELD_TYPE_STR, BUNDLE_FIELD_TYPE_VARCHAR, or BUNDLE_FIELD_TYPE_NODEREF with BUNDLE_FIELD_INDEX_HASH. All values in this type of field will be indexed for quick lookup (O(1)) using getbundleindexentries(). This type of field is only recommended for use with bundles that rarely, if ever, change size while the model is running.

You can optionally combine any of the above values with BUNDLE_FIELD_NULLABLE, to allow those fields to contain null values. If a field is nullable, you can pass a null Variant in to setbundlevalue(), and it is possible to get a null Variant from getbundlevalue().
Example
addbundlefield(x, "Object Name", BUNDLE_FIELD_TYPE_STR | BUNDLE_FIELD_NULLABLE, 64);
addcommand (obj codenode, str commandname, str description, str parameters, str example [, str cppprefix, str shortdescription])

Example
addsystemcontrolleritem(current.centerObjects[1],0,1,1,0);
addtablecol (str/num/node table [, num column, num datatype])
Deprecated, use Table.addCol()

Example
addtoeventtypelegend (str name, num parameter, num value, str legendname)
Description
The eventtype legend allows you to associate a string with a given value for a given parameter in that eventtype. Passing a negative number for 'parameter' allows you to add a preceeding string to explain the parameter. If the 'parameter' is negative and the 'value' is -1, then it assumes the number is a pointer to a node and will display the node's path as a string.
Example
addtoeventtypelegend(index,-1,-1,"resource: "); // for p1, display the text "resource: " and display the path for the object
addtoeventtypelegend(index,-2,0,"covermode: "); // for p2, display the text "covermode: "
addtoeventtypelegend(index,2,1,"YellowToGreen"); // for p2, a value of 1 should display "YellowToGreen" instead of the number 1
addtoeventtypelegend(index,2,2,"RedToGreen"); // for p2, a value of 2 should display "RedToGreen" instead of the number 2
addtoeventtypelegend(index,3,0,""); // for p3, this makes zeroes blank

AGV_CURRENT_CP - Returns the agv's current control point
AGV_ORIGIN_CP - Returns the agv's origin control point
AGV_INTERMEDIATE_DEST_CP - Returns the agv's intermediate destination control point

AGV_START_RECHARGE - Starts the agv recharging. Returns the time it will take to recharge to full capacity.
AGV_RECHARGE_TO_LEVEL - Explicitly set's the agv's battery level to p1 (0 - 100).
AGV_ADD_ALLOC_POINT - Should be called from the travel initialization trigger. Manually adds a control point/control area for allocation, i.e. a control point or control area that would not otherwise need to be allocated as part of the agv's current travel path. The control point/control area is passed as p1, and the distance at which it must be allocated is passed as p2. The command will return a reference to a node that represents that allocation. Use AGV_SET_ALLOC_POINT_DEALLOC_DIST and AGV_SET_CAN_STOP_AT_ALLOC_POINT to specify further data on that allocation point.
AGV_SET_ALLOC_POINT_DEALLOC_DIST - For a manual allocation point that's been added, this sets the travel distance at which the agv can deallocate the object. You should call this at some point after adding the allocation, so that the object will be properly deallocated. p1 is a reference to the allocation point node returned by AGV_ADD_ALLOC_POINT, and p2 is the deallocation distance.
AGV_SET_CAN_STOP_AT_ALLOC_POINT - Sets whether or not the agv can stop at a manually added allocation point. The default is no, i.e. the agv will not stop at the stop distance, but will continue to the next stoppable point before attempting to allocate the object. Setting this to 1 will allow the agv to stop at the manual allocation point to allocate ahead. p1 is a reference to the allocation point node returned by AGV_ADD_ALLOC_POINT, and p2 is 1 or 0.
AGV_ATTACH_TRAILER - Manually attaches a trailer to the AGV. p1: the object to attach. p2: the trailer gap to apply. p3: If 1, the trailer will be attached behind the AGV (attach to the AGV's tail), if 0, the trailer be attached ahead of the AGV (attach to the AGV's head). p4: If 1, the trailer will automatically be detached when the object exits the AGV, if 0, the trailer should be manually detached.
AGV_DETACH_TRAILER - Manually detaches a trailer from the AGV. p1: the object that is attached as a trailer.
AGV_SPEED - Returns the agv's current speed
AGV_PROXIMITY_STATE - Returns 1 if the agv is blocked by proximity on an accumulating path, 0 otherwise.
AGV_ACCUM_AHEAD_AGV - Returns the agv ahead of this agv on an accumulating path, if one exists.
Example
agvinfo(agv, AGV_DEST_CP);

REDIRECT_AND_WAIT - if not redirected before arrival, the agv will wait at the destination until redirected
REDIRECT_AS_FINAL - the destination becomes the new final destination for the agv REDIRECT_AND_CONTINUE_ON_ARRIVAL - the agv will continue to the final destination after arriving at the intermediate destination
REDIRECT_AND_CONTINUE_ON_PRE_ARRIVAL - the agv will continue to the final destination after pre-arriving at the intermediate destination (it will not decelerate to a stop)
Example
agvredirect(agv, controlpoint, 1);

bcgetitemkinematics (obj basicconveyor, obj item, num kinematictype {0-main kinematic : 1-time dependent : 2-convey dependent})
Deprecated, legacy conveyors are no longer supported
Description
Deprecated, Legacy conveyors are no longer supported.

This command is used in conjunction with the BasicConveyor object.

The bcgetitemkinematics command is used to obtain a reference to one of the three kinematics associated with a flowitem traveling on a BasicConveyor:

 0 = The main convey state kinematics. You may get kinematic information from this, but do not change the kinematic by adding kinematics or initializing it.

 1 = A user-definable kinematics that is dependent on simulation time.

 2 = A user-definable kinematics that is dependent on the convey position of the flowitem on the conveyor.

 The two user-definable kinematics are available for the user to set up customized kinematic motion in addition to traveling down the length of the conveyor. Use bcgetitemkinematics to get a reference to the desired kinematics node, and then use standard initkinematics() and addkinematic() commands as normal. You will need to use the alternative initkinematics parameter list: initkinematics(node, x, y, z, rx, ry, rz, managerots, localcoords). Also, if you add kinematics to the type 2 convey depend kinematic node, bear in mind that all time units for that kinematic no longer apply to actual simulation time units. Instead, they are interpretted as "convey units". For example, a speed of 5 is no longer 5 units per time unit, but is instead 5 units per conveyed unit. Acceleration is not distance per time squared, but distance per conveyed unit squared. Start times are no longer a time to start the kinematic, but a position along the conveyor to start the kinematic at. As an example, let's say you add a kinematic to the convey dependent kinematic node to travel 1 unit in the y direction with "start time" 5 and "max speed" 0.5. What that translates to for the convey dependent kinematic is that the item will start traveling in the y direction once it reaches 5 units along the conveyor. Also, for every unit that it travels down the length of the conveyor, it will travel 0.5 units in the y direction (0.5 y units per convey unit). Thus it will finish the y kinematic once it has travelled 7 units down the conveyor. If the item is blocked in the middle because of accumulation, say at convey position 6, then its y kinematic will also stop, and not resume until the item resumes along the conveyor.

 See bcsetitemconveystate command documentation for a general description of the BasicConveyor object.
Example
treenode kin = bcgetitemkinematics(current, item, 2);
treenode kin2 = bcgetitemkinematics(current, item, 1);

 initkinematics(kin, 0,0,0, 0,0,0, 0,0);
addkinematic(kin, 0,1,1,0.5,1,1,0,0, 5, KINEMATIC_TRAVEL);
initkinematics(kin2, 0,0,0, 0,0,0, 0,0);
addkinematic(kin2, 0,0,720,360,0,0,0,0, time()+5.0, KINEMATIC_ROTATE);
bcgetitemposition (obj basicconveyor, obj item)
Deprecated, legacy conveyors are no longer supported
Description
Deprecated, Legacy conveyors are no longer supported.

This command is used in conjunction with the BasicConveyor object

The bcgetitemposition command returns the current position of an item on a BasicConveyor object. The position is measured along the conveyor's length from the head of the conveyor to the flowitem's edge furthest from the head of the conveyor.

See bcsetitemconveystate command documentation for a general description of the BasicConveyor object.
Example
bcgetitemposition(current,current.first);
bcsetdirection (obj basicconveyor, num direction)
Deprecated, legacy conveyors are no longer supported
Description
Deprecated, Legacy conveyors are no longer supported.

This command is used in conjunction with the BasicConveyor object.

 The bcsetdirection command stops all flowitems on the conveyor and sets the direction of travel to 1=forward and 0=reverse. All flowitems will need to have their convey state reset with the bcsetitemconveystate() command before they will begin moving again. The example below shows how to stop the conveyor, and then have all the flowitems accelerate up to a speed of 1 in the reverse direction. Any additional item kinematics will still be active after a direction change.

 See bcsetitemconveystate command documentation for a general description of the BasicConveyor object.
Example
bcsetdirection(so(),0);
for(int i = 1; i <= so().subnodes.length; i++)
{
     treenode item = so().subnodes[i];
     bcsetitemconveystate(so(), item, bcgetitemposition(so(), item), 0, 1, 0.2);
}
bcsetitemconveystate (obj basicconveyor, obj item, num startpoint, num startspeed, num targetspeed, num accdec)
Deprecated, legacy conveyors are no longer supported
Description
Deprecated, Legacy conveyors are no longer supported.

This command is used in conjunction with the BasicConveyor object.

 The BasicConveyor object allows flowitems to be moved in and out of the conveyor at any time and at any location. Each flowitem on the BasicConveyor can be assigned and re-assigned its own kinematic profile defining how the flowitem is to move along the conveyor. When one flowitem overtakes another flowitem on the conveyor which is either stopped or traveling at a slower speed, it will slow down immediately to match that flowitem's speed. Although flowitems may travel in either direction along the conveyor, all flowitems will travel in the same direction at any given time. The travel direction of the conveyor is set with the bcsetdirection() command. As flowitems are moved in and out of the conveyor, other flowitems on the conveyor are aware of the increase or decrease in available space along the conveyor, and will accumulate naturally. After a flowitem enters the conveyor, either indirectly with the receiveitem() command or directly with the moveobject() command; it is necessary to define the flowitem's initial kinematic profile. This profile is refered to as the flowitem's "convey state", and it is set with the bcsetitemconveystate() command. The convey state for a flowitem can be set multiple times if desired. The following are definitions for the parameters used to define the convey state of a flowitem:

 basicconveyor = A reference to the conveyor.

 item = A reference to the flowitem.

 startpoint = The starting location for the flowitem as measured from the beginning of the conveyor, along the conveyor's length to the flowitem's edge furthest from the head of the conveyor (the leading edge if the conveyor's direction is forward, the trailing edge if the conveyor's direction is backward).

 startspeed = The initial speed the flowitem will begin traveling at.

 targetspeed = The target speed the flowitem will try to achieve. If the targetspeed is greater than the startspeed, then the flowitem will accelerate up to the target speed; otherwise it will decelerate down to the target speed. If both the startspeed and the targetspeed are set to 0, the flowitem will be positioned at the startpoint, and will not move.

 accdec = The acceleration or deceleration used to achieve the target speed over time. A value of 0 indicates infinite acceleration/deceleration; or in other words the flowitem will reach it's targetspeed immediately.

 No destination or termination speed is required, because the flowitems continue traveling along the conveyor until they either reach the end of the conveyor, run into another flowitem, or their convey state is changed again. The BasicConveyor allows multiple "Decision Points" to be defined along its length. These trigger points are convenient locations to update the convey state of a flowitem. In addition to the main convey state kinematic assigned to the flowitem with the bcsetitemconveystate() command, a flowitem has two other kinematic structures associated with it that may be used to apply custom kinematic motion (translation or rotation) in addition to the travel motion along the conveyor. One of the kinematic structures is based on simulated time units, and the other is based on distance units along the length of the conveyor. To access these kinematic structures, use the bcgetitemkinematics() command, then use the initkinematics() and addkinematic() commands to create the custom kinematic motion desired. See bcgetitemkinematics() command documentation for more information.
Example
bcsetitemconveystate(current, item, position, 0, 60, 0);
beginaggregatedundo (obj view, str description)

p is the probability that a will be returned;  where p∈ ( 0, 100 )
100 −p is the probability that b will be returned.
a∈ ( - ∞, ∞ )
b∈ ( - ∞, ∞ )
stream is a reference to one of FlexSim's random number streams {0,1,2,...}

Outputs:
range = { a , b }
mean = ( ap + b(100−p) ) ⁄ 100
variance = (p⁄100)(1 −p⁄100) when a=1 and b=0

Possible Applications:
Used to model a random occurrence that has two possible outcomes such as a pass/fail test. It is possible to generate more than two values by nesting bernoulli commands; however, it is better to use empirical distributions in these cases.

Comments:
The bernoulli(p, 1, 0) and binomial(1, p) distributions are the same.
Example
treenode curoperator = current.centerObjects[bernoulli(90,1,2,1)];

 The bernoulli command in this example has a 90 percent probability of returning 1 otherwise it will return 2, using random number stream 1. It is used within a centerObject reference such that 90 percent of the time curoperator references the object connected to center port 1 of the current object, otherwise curoperator references the object connected to center port 2.
beta (num min, num max, num shape1, num shape2[, num stream])
Returns a random sample from a beta distribution
Description
beta( a, b, α1, α2, stream ) is a bounded continuous probability distribution.

Inputs:
a is the lower-endpoint parameter ∈ ( - ∞, ∞ )
b is the upper-endpoint parameter( b > a )
α1 is the 1st  shape parameter ( 0, ∞ )
α2 is the 2nd shape parameter ( 0, ∞ )
stream is a reference to one of FlexSim's random number streams {0,1,2,...}

Outputs:
range = ( a , b )
mean = a + α1(b−a) ⁄ (α1 + α2)
variance = α1α2(b−a)²⁄ (α1 + α2)²(α1 + α2 + 1)

Probability Density Functions:



Possible Applications:
The beta distribution is often used to model task durations in the absence of real data because it can be definitively bounded between a minimum and maximum value, and it can take on a number of different probability density shapes depending on the two shape parameters used. For most real world task durations, the density shape will have a longer right tail than a left, so if you know the mean μ and the mode (most likely value) m, you can back calculate suitable shape parameters with the following equations:

α1 ≅ ( μ−a)(2m−a−b) ⁄ (m−μ)(b−a)

α2 ≅ α1(b−μ) ⁄ (μ−a)

Comments:
The beta( a, b, 1, 1) and uniform( a, b) distributions are the same.
The density is symmetric about (a + b) ⁄ 2 when α1 = α2.
The density will have a hump and longer right tail when α2 > α1 > 1.
The mean and mode are equal when α1 = α2 > 1.
Example
double ptime = beta(8, 12, 1.3, 3, 5);

The ptime variable is set equal to a beta distribution having a minimum value of 8, a maximum value of 12, and shape factors of 1.3 and 3 for α1 and α2 respectively. FlexSim's random stream number 5 will be used to generate variates from the distribution. The distribution density will have a nice humped curve with a long right tail.
bindtexture (num textureid)
Description
This function is used in an OpenGL call sequence. When OpenGL commands are being used to draw a scene, this command will bind the texture loaded into FlexSim with the index textureid. Once bound, a texture will be used to render any polygons drawn subsequently. Texture mapping is the application (or mapping) of an image (or texture) to the surface of a polygon or other graphics primitive.
Example
bindtexture(10)

 Use loaded texture with index number 10 for rendering any subsequent polygons
binomial (num trials, num prob[, num stream])
Returns a random sample from a binomial distribution
Description
binomial( t, p, stream ) is a discrete probability distribution used to represent the number of successes in t independent Bernoulli trials with probability p of sucess on each trial.

Inputs:
t is the number of independent trials { 1, 2, ..., ∞ }.
p is the probability of success for any given trial (0, 100)
stream is a reference to one of FlexSim's random number streams {0,1,2,...}

Outputs:
range = { 0, 1, 2, ..., t }
mean = tp⁄ 100
variance = t ( p⁄ 100 )( 1 −p⁄ 100 )

Possible Applications:
The binomial distribution is useful for modeling the number of defective parts in a batch of size t, or the actual number of people in random size groups, or maybe the number of items ordered from inventory.

Comments:
The binomial(1, p ) and bernoulli( p, 1, 0 ) distributions are the same.
The binomial( t, p ) distribution is symmetric when p = 50 percent.
Example
int fparts = binomial(item.batchsize, 10, 5);

 The number of failed parts will be written to the fparts variable based on a 10% probability that any given part will fail within a batch quantity defined by a label on the flowitem named "batchsize". FlexSim's random stream number 5 will be used to generate variates from the distribution.

Deprecated, use Table class
Description
This command is deprecated. Use the Table class instead.
Example
cempirical (str/node/num table[, num stream])
Returns a random sample from a continuous empirical distribution
Description
A continuous empirical distribution with percentages and values defined in the table specified.

 Empirical distributions reference tables created by the user that contain a list of values and probability percentages associated with each value. Probability percentages must be entered in column 1 starting with row 1 of the table, and the associated values are entered in column 2. The table may have as many rows as needed to define as many values as desired. The percents are entered as numbers between 0 and 100, and should add up to a total of 100 percent; otherwise any values defined after a cumulative percentage of 100 is reached will never be returned.

 There are three commands in FlexSim that can be used to generate random variates from the empirical distributions defined in tables. The three commands are dempirical(), empirical() and cempirical(). The first one is a discrete distribution and will return the explicit values listed in the table. The next two are bounded continuous distributions, meaning they return a continous number within a range. The values in column 2 for the continuous distributions must be in ascending order because they will interpolate values between two adjacent values in the table.

 Let's assume we have a table with 4 rows and 2 columns. In column one are the percentages 10, 20, 30 and 40 adding up to 100 percent. In column two are the values 0.1, 0.2, 0.3 and 0.4. Now let's see the differences between the discrete empirical command and the two continuous empirical commands. The discrete command will only generate random variates that match exactly the values that were entered into column two of the table. The continuous commands will generate random variates that are real numbers uniformly distributed between two adjacent numbers in column two of the table. The difference between the two continuous commands is in how the bounds of the uniform ranges are defined.

 The command dempirical("mytable") will return the number 0.1 for ten percent of the samples, the number 0.2 for twenty percent of the samples, the number 0.3 for thirty percent of the samples, and the number 0.4 for forty percent of the samples assuming a very large sample set.

 The command empirical("mytable") will return a number uniformly distributed between 0.1 and 0.2 for ten percent of the samples, a number uniformly distributed between 0.2 and 0.3 for twenty percent of the samples, a number uniformly distributed between 0.3 and 0.4 for thirty percent of the samples and a number uniformly distributed between 0.4 and 0.4 for forty percent of the samples. If you want the last forty percent to be between 0.4 and 0.5 instead of 0.4, add a 5th row with column one being a value of 0 and column two being 0.5 or the desired upper bound.

 The command cempirical("mytable") will return a number uniformly distributed between 0.0 and 0.1 for ten percent of the samples, a number uniformly distributed between 0.1 and 0.2 for twenty percent of the samples, a number uniformly distributed between 0.2 and 0.3 for thirty percent of the samples and a number uniformly distributed between 0.3 and 0.4 for forty percent of the samples. You can define a lower bound for the first ten percent to be a value different than 0.0 by adding a row to the beginning of the table (row 1) where column one is a value of 0 and column two is 0.05 or the desired lower bound.

 Here is a summary in tabular form showing the possible return values ("x") for each of the three distribution functions:



 Here is an example of adding a "dummy" first row so that cempirical() starts at 0.05 instead of 0.0 (notice that row 1 has a probability of 0 percent):



 Here is an example of adding a "dummy" last row so that empirical() has a range between each value including the last (any number can be entered for the percent of the last row because the percents already add up to 100% with the previous row, so it doesn't matter what it is):



 When using ExpertFit to determine an empirical distribution that matches your data, you need to be aware that if your data has been defined as integers, then ExpertFit will fit it for use with dempirical(), and if your data has been defined as real numbers, ExpertFit will fit it for use with empirical(). When your data set is composed of real numbers, ExpertFit will show the same percentage for the last value as for the previous to last value, but you'll notice that the percents add up to 100% with the second to last entry.
Example
cempirical("mytable", 5);

Returns a random variate from a continuous empirical distribution defined in a global table named "mytable" using random number stream 5.

cempirical(current.labels["ptime"] 5);

Returns a random variate from a continuous empirical distribution defined in a node table defined on a label named "ptime" of the current object, and using random number stream 5.
centerobject (obj object, num centerportnum)
Deprecated, use Object.centerObjects[]
Description
This command is deprecated. Use Object.centerObjects[] instead.

 Reference the object connected to an object's center port.
Example
changeconveyorspeed (obj conveyor, num newspeed )
Deprecated, use conveyor.targetSpeed
Description
This command is deprecated. Legacy conveyors are no longer supported. Use Conveyor.targetSpeed instead.

 Changes the speed of the conveyor to newspeed.
Example
changeconveyorspeed(current, 4);
This example changes the conveyor's speed to 4.
changedisplay (num width, num height, num depth, num fullscreen, num test)
Change resolution
Description
Change resolution
Example
changedisplay(1024,768,0,0,0)
changetask (obj tasksequence, num taskrank, num type [, obj involved1, obj involved2 , num var1, num var2, num var3, num var4] )
Dynamically change a task in tasksequence
Description
This command is deprecated. Use the TaskSequence and TaskSequence.Task class methods and properties instead. This command lets you change a task dynamically. For example, if you want an operator to travel to object B instead of traveling to object A, but a task has already been created for him to travel to object A, you can use this command to change the task.

The first parameter (tasksequence) specifies the tasksequence containing the task. The second parameter (taskrank) specifies the rank of the task in the tasksequence. All other parameters are the same as for the inserttask command.

This command should only be executed if the task is not the currently active task in the task sequence!
Example
changetask(gettasksequence(current, 0), 4, TASKTYPE_TRAVEL, current.centerObjects[5]);

This example changes the fourth task in the current object's active task sequence to a travel task to travel to the object connected to the 5th center port of the current object.
checkdllconnection (node dllnode, num force)
Returns 1 if the node is properly connected with a dll function
Description
Returns 1 if the node is properly connected with a dll function. Otherwise returns 0. If force is 1, then if the node is not connected, it will attempt to bind it to a dll function, and will return 1 if successful, 0 if not. The node must be toggled as DLL and have proper data specifying the path to the dll and the function name.
Example
if(!checkdllconnection(getvarnode(current, "exittrigger"), 1)) msg("DLL Error","Error connecting to dll.")

This will attempt to connect and object's exit trigger node with a dll function, and will print a message if it is unsuccessful.
checkforexistingview (obj view [, num mode])
Description
For developer use. Checks to see if there are any currently active windows that match this window.
Compares the beginning of each name of each window in the active view node with the beginning of the name of the specified view.
Along with comparing the beginning of the names, this compares each objectfocus as well.
If mode is specified and is not 0, it will compare the viewfocus instead of the objectfocus.
Example
checkforexistingview(c)
classobject (obj object)
Returns the class object of an instance
Description
Returns the class object of an instance.
Example
if(classobject(current) == library().find("?Processor"))
{
pt("Processor1 is an instance of the Processor class.");pr();
}

 This prints a message to the output console if current is a Processor.
cleannodeflexscript (node startnode)
Description
For developer use. This command recursively deletes Flexscript trees starting at the node specified.
Example
cleannodeflexscript(model());

 This cleans all the Flexscript nodes in the model.
clearbundle (node datanode[, num resetflags = 0])
Clears all bundle data
Description
Clears the bundle data associated with datanode. This will clear all entries as well as all fields in the bundle. resetflags is a bitwise mask for flags to initialize the bundle by. Valid values are:
BUNDLE_FLAG_UNPAGED = 0x1 - The bundle's entries will be stored in an unpaged, contiguous block of memory.
BUNDLE_FLAG_IR_OPT = 0x10 - The bundle will use additional memory (32 bits per row) to improve insert/remove performance for rows in the middle of the bundle.
Example
clearbundle(x);
clearconsole ()
Clears the output console
Description
This command clears the output console if it is open. The output console is where output from the pt(), pf(), and pr() commands is printed.
Example
if (v_printerror == 1)
{
clearconsole();
pt("An Error occurred");
}

 This clears the output console and prints a simple error message to it if the variable called printerror is equal to 1.
clearcontents (node thenode)
Deprecated, use treenode.subnodes.clear()
Description
This command is deprecated. Use treenode.subnodes.clear() instead.

 Destroys all of the objects/nodes under the node.
Example
clearfullhistory (int resetuniqueid)
Deprecated
Description
This command is deprecated. Deletes all of the data that has been collected by the Full History system. If resetuniqueid is 1, then the unique IDs of the flowitems that are created after this command is called will being again at 1. Typically, this parameter should be 0, as that will continue numbering so that old flowitems are not confused with new flowitems.
Example
clearfullhistory(0);
clearglobaltable (str/node/num table)
Deprecated, use Table class
Description
This command is deprecated. Use the Table class instead.
Example
clearundohistory ([obj view])
Description

Example
clearundohistory(view);
clickcode ()
Description
For developer use. Returns the type of click in a view. Used in the OnClick event.

 DOUBLE_CLICK returns 1
LEFT_PRESS returns 2
LEFT_RELEASE returns 3
RIGHT_PRESS returns 4
RIGHT_RELEASE returns 5
Example
if(clickcode()==2)
{
pt("Clicked!!");pr();
}

 This prints the statement "Clicked!!" to the output console when the left mouse button is pressed.
clientclose (num socket)
Closes the client socket
Description
This command closes the client socket specified as socket.
It must be called sometime after clientcreate(). Once a socket is closed, nothing can read from it or write to it.
The socket number may be reused again by a later call to clientcreate(). This function returns true if the socket closes correctly.
Example
clientclose(1);
clientconnect (num socket, str hostname, num port)
Attempts to connect the client socket
Description
This command attempts to connect the socket specified by socket to a server running on the machine called hostname, which is listening on the port specified.

The number passed as socket is the number that was previously returned by clientcreate(). The string passed as hostname can be either the computer's name (if it is on the same network as the client) or its IP address. This command should not be called until after a successful call to clientcreate() is made. If the socket does not connect, then it is closed and clientcreate() will have to be called again to reopen it. This functions returns true if the socket connects successfully.
Example
clientconnect(1,"localhost",1880);
clientcreate ()
Creates a new client socket with TCP/IP protocol
Description
This command creates a new client socket that is set to communicate using the TCP/IP protocol. FlexSim can create up to fifty client sockets at one time.

Each client can be connected to a different server. This function returns a number that must be stored by the model to reference the socket that was created.

If an error occurs, this function returns 0.
Example
int socknum = clientcreate();
clientreceive (num socket, str buffer, num buffersize, num noblock[1/0])
Receives data sent to the socket
Description
This command receives data that has been sent to the socket specified as socket. The value of socket is the number that is returned by clientcreate(). This command operates differently in flexscript vs. c++. In c++, buffer must be a valid pointer to a char* destination into which the read bytes will be copied. The return value will be the total number of bytes received. Up to bufsize bytes from the clients message will be read and stored in the preallocated character array called buf. In flexscript, however, buffer should be passed as NULL, and the return value will be the actual string that is received. If noblocking = 1, then this command does not block FlexSim program execution, but if noblocking = 0, FlexSim program execution will block (freeze) until something is received from the client.
Example
c++: int bytes = clientreceive(1,Buf,15,0);
flexscript: string readstr = clientreceive(1, NULL, 15, 0);
clientsend (num socket, str message[, num charlength])
Sends a message across the socket
Description
This command sends a message across the socket specified as socket. The value passed as socket is the number returned by clientcreate(). The charlength is the length of the string being passed and is usually optional. Needed only if the string being sent has NULL characters in it.
Example
clientsend(1,"REQ:service");
closeallip (obj object)
Close all input ports of object
Description
Close all input ports of object. Closing all input ports of an object will block entry to the object. Modelers should only use this command when working with fluid objects because the internal behavior of discrete objects controls the opening and closing of their ports, and therefore this command may be overridden. For discrete objects the modeler is referred to closeinput() and stopinput().
Example
closeallip(current)
closeallop (obj object)
Close all output ports of object
Description
Close all output ports of object. Closing all output ports of an object will block the exit of that object. Modelers should only use this command when working with fluid objects because the internal behavior of discrete objects controls the opening and closing of their ports, and therefore this command may be overridden. For discrete objects the modeler is referred to closeoutput() and stopoutput().
Example
closeallop(current)
closeinput (obj object)
Deprecated, use Object.input.close()
Description
This command is deprecated. Use Use Object.input.close() instead.

 This command blocks the input of the object. Only the input ports themselves, or the input in general needs to be closed to block entry. When port connections are displayed with sufficient size in the view window, you will see a small red bar drawn across all the input ports (squares) for the object, signifying the input ports are blocked. Individual ports may still be open and drawn in green, but entry to the object is still blocked because of the red bar. Compare this command with stopinput().
Example
if (current.subnodes.length == getvarnum(current,"maxcontent")
closeinput(current);

 This blocks the input ports of current when it has too many objects inside it.
closeip (obj object, num inputportnum)
Close one input port of object
Description
Close just inputportnum of object. Closing an input port of an object will block entry to the object through that port. Modelers should only use this command when working with fluid objects because the internal behavior of discrete objects controls the opening and closing of their ports, and therefore this command may be overridden. For discrete objects the modeler is referred to closeinput() and stopinput().
Example
closeip(current,1)
closenodeedge (obj object, num edgenum)
Closes entry to the networknode's edge
Description
Closes entry to the networknode's specified edge number.
The edge's color will turn orange indicating it is closed.
Open or close status of an edge will only be checked by a traveler
when traveling from one node to the next (not when entering a node from an offset)
Example
closenodeedge(current.centerObjects[1], 3);
closeop (obj object, num outputportnum)
Close one output port of object
Description
Close just outputportnum of object. Closing an output port of an object will block the exit from the object through that port. Modelers should only use this command when working with fluid objects because the internal behavior of discrete objects controls the opening and closing of their ports, and therefore this command may be overridden. For discrete objects the modeler is referred to closeoutput() and stopoutput().
Example
closeop(current,1)
closeoutput (obj object)
Deprecated, use Object.output.close()
Description
This command is deprecated. Use Object.output.close() instead.

 This command blocks the output of the object. Only the output ports themselves, or the output in general needs to be closed to block the exit. When port connections are displayed with sufficient size in the view window, you will see a small red bar drawn across all the output ports (squares) for the object, signifying the output ports are blocked. Individual ports may still be open and drawn in green, but exit from the object is still blocked because of the red bar. Compare this command with stopoutput().
Example
if (current.subnodes.length == current.mincontent)
closeoutput(current);

 This blocks the output ports of current, if current has too few objects inside it.
closeview (node viewnode)
Description
For developer use. This command closes the view specified as viewnode. If viewnode is not a viewwindow or GUI, this command does nothing. The view is not removed from the active views folder, however. Use destroyobject() to remove it.
Example
treenode activewindows = views().find("active");
while (activewindows.subnodes.length != 0)
{
closeview(activewindows.first);
}

 This closes all of the windows that are in the active node of the views tree. This will generally close all of the windows that are currently open.
cm (num centimeters)
Gets the number of meters in the number of centimeters
Description
Returns the number of meters in the specified number of centimeters.
Example
cm(3)
cmdcompile ()
Description

Load a session by name.
Example
cmdloadsession("c:/mysession.fss")
cmdloadtree (obj desttree, str filename [, num nobuild])
Description
For developer use.

Load a tree by file path into desttree. By default, after loading, all flexscript will be built. If nobuild is 1, flexscript will not be built. Set nobuild to 1 if you are executing this command from a script node that is toggled as flexscript, or else your script will not finish properly.
Example
cmdloadtree(node("MAIN:/project/model/2"),"c:/mytree.t"))

Example
cpallocate(controlPoint, current, 1);
cpconnection (obj controlpoint/object, num/str connection, num rank)
Description
Returns a control point connection. Also, if connection is a string and controlpoint and rank are both 0, then this command will return the index of the given connection. This is for speed, so that you can subsequently use a number for the connection.
Example
cpconnection(cp, "ForwardTo", 1) Returns the first ForwardTo connection on cp
cpconnection(cp, "LookForWork>NextLookForWork", 1) Traverses two connections to find an object. This is the same as cpconnection(cpconnection(cp, "LookForWork", 1), "NextLookForWork", 1)

createcopy (node thenode, node container [, num samename, num inobject, num cached, num replace])
Copies thenode into the specified container
Description
Copy thenode into the node specified as container. This command is different from createinstance() in that it does not attempt to establish any links between thenode and any class. If an instantiation is required, use createinstance() instead.

If samename is 1, the copy will have the same name as thenode.

If samename is 0, the newly created node's name will be thenode's name with a random number added to the end.

 If inobject is 1, the copy will be created in the object data portion of the container. If the container does not have object data, the command does nothing.

 If cached is 1, a pre-cached version of the node will be copied. This is generally faster.

 If replace is 1, the copy will overwrite container, instead of being placed inside it.

 If those parameters are not specified, they default to 0.
Example
createcopy(Model.find("Tools/FlowItemBin/7/1"), current)
createcoupling (node container1, node container2)

This command creates a task sequence for the object specified by dispatcher that causes it to pause its current task for delaytime seconds. During the time that it is delayed, it will be in the state specified by state. The task sequence will be given a priority of priority and a preempting value of preempting. The possible values for preempting are:

0 - PREEMPT_NOT
1 - PREEMPT_ONLY
2 - PREEMPT_AND_ABORT_ACTIVE
3 - PREEMPT_AND_ABORT_ALL
Example
createdelaytask(current.centerObjects[1], 25, SCHEDULED_DOWN, 1, PREEMPT_NOT);
createemptytasksequence (obj dispatcher, num priority, num preempting)
Creates a new task sequence in the dispatcher's queue and returns a reference to it
Description
This command is deprecated. Use TaskSequence.create() instead. Creates an empty task sequence in the dispatcher's tasksequence queue. Tasks should be added to this task sequence once it is created, using the inserttask command. The task sequence is dispatched with the dispatchtasksequence command. This command returns a pointer to the newly created tasksequence node. The possible values for preempting are:

0 - PREEMPT_NOT
1 - PREEMPT_ONLY
2 - PREEMPT_AND_ABORT_ACTIVE
3 - PREEMPT_AND_ABORT_ALL
Example
createemptytasksequence(current.centerObjects[1], 1, PREEMPT_NOT);
createevent (obj object, num time, num code[, str data, node involved])
Description
For developer use. This command creates an event that will occur sometime in the future in the model's run. The event will be created for the object specified by object. It will occur time seconds from the time that this command is called. If an event needs to occur that the same simulation time that it was created at, time should be 0. When the event occurs, the OnTimerEvent event function of the class of object will be called. This function will be passed code, data, and involved. These values can be accessed in OnTimerEvent as eventcode, eventdata, and i. Generally, eventcode is used to determine what type of event is being created or executed. Eventdata is used as a description of the event for the user's benefit. It is generally not important to the execution of OnTimerEvent. Any objects that are involved in the event, such as a flowitem that is entering or exiting, are passed as involved and are referenced in OnTimerEvent as i. There are predefined values for code that the user should use listed below:

 1 - EVENT_OPENINPUTS
2 - EVENT_OPENOUTPUTS
3 - EVENT_PROCESSFINISH
4 - EVENT_CREATEPART
5 - EVENT_DESTROYPRODUCT
6 - EVENT_CONVEYEND
7 - EVENT_BEGINLOADTIME
8 - EVENT_BEGINUNLOADTIME
9 - EVENT_ENDLOADTIME
10 - EVENT_ENDUNLOADTIME
11 - EVENT_ENDDELAYTIME
12 - EVENT_BEGINDOWNTIME
13 - EVENT_ENDDOWNTIME
14 - EVENT_ENDWAITTIME
15 - EVENT_MEETBATCHQTY
16 - EVENT_ENDTRAVELTIME
17 - EVENT_ENDSETUP

 If a user wishes to create their own types of events, they should use values for code that are greater than 100. See also eventcode and eventdata.
Example
if (current.subnodes.length >= current.mincontent)
{
createevent(current,5,EVENT_OPENOUTPUTS,"openoutputs",involved);
}

 This creates an event that will occur in 5 simulation seconds that will open the output ports of the object specified as current, for the flowitem specified by involved, if the content of current is less than the label called mincontent of the object referenced by current.
createglobaltasksequence (str name, obj dispatcher [, obj dp1, obj dp2, obj dp3, obj dp4, obj dp5])

Description
This command is deprecated. Use Process Flow instead.

 Creates an instance of the named global task sequence with the given dynamic parameters 1-5 and dispatches it to the specified dispatcher. Returns a reference to the created global task sequence. Note that this does not dispatch the task sequence. You need to dispatch it yourself using dispatchtasksequence().
Example
treenode ts = createglobaltasksequence("GlobalTS", current.centerObjects[1])
dispatchtasksequence(ts)
createinstance (obj class, obj location)
Description
For developer use.

 This command creates an instance of the class specified as class and places it in the object specified as location. The instance will be given a name that is the name of the class followed by a number. The instance will have all of the variables and attributes of class and it's superclasses. Nodes in the behavior node will not be copied into the instance, as they apply to all instances of the class. The object passed as class should be in the library. Generally, location is the model. The library and the model can be easily referenced using the library() and model() commands.
Example
createinstance(library().find("?Source"), model());
This creates an instance of the Source class in the model.
createloadtask (obj taskexecuter, obj destination, obj flowitem, num priority, num preempting)
Deprecated, use Process Flow instead
Description

0 - PREEMPT_NOT
1 - PREEMPT_ONLY
2 - PREEMPT_AND_ABORT_ACTIVE
3 - PREEMPT_AND_ABORT_ALL
Example
createloadtask(current.centerObjects[1],current.centerObjects[2],item, 1, PREEMPT_NOT);
createpopup (str viewpath, str objectfocus, str viewfocus, obj relativeto, num x, num y, num sx, num sy)
Creates a new popup window
Description
Similar to the createview command in that it creates a new window. However, FlexSim manages this window so that whenever the user clicks outside of the window, the window will be closed. Code template pop-ups use this command to create a drop-down in which you can edit the template code. The pop-up view must contain a style attribute with the WS_POPUP style. You also specify a view node "relative to" which the popup's location will be set (usually whatever view you're writing code on). Also specify an offset location in pixels from relativeto's top-left corner, and a size of the pop-up.
Example
treenode combobox = c.find("../pickoptions");
createpopup(
     "VIEW:/standardviews/picklisttemplate",
     combobox.find(">pickprimary+").getPath(0,1),
     combocurrentnode(combobox).getPath(0,1),
     combobox,
     0,20,combobox.location.x, 150
);
This code is similar to what is used to create the template code pop-up for many of FlexSim's edit fields.
createsendmessagetask (obj taskexecuter, obj receiver, num priority, num preempting , num param1, num param2, num param3)
Deprecated, use Process Flow instead
Description
This command is deprecated. Use Process Flow instead.

 This command creates a task sequence on the object specifies as dispatcher that causes it to send a message to the object specified as receiver. The OnMessage trigger of the receiving object will be executed when the message is sent. The values passed as param1, param2, and param3 will be available in the trigger function using the param() command. This task sequence will be given a priority of priority and a preempting value of preempting. The possible values for preempting are:

0 - PREEMPT_NOT
1 - PREEMPT_ONLY
2 - PREEMPT_AND_ABORT_ACTIVE
3 - PREEMPT_AND_ABORT_ALL
Example
createsendmessagetask(current, current.centerObjects[1],1,PREEMPT_NOT,5, 6, 7);

createtraveltoloctask (obj dispatcher, num relativeloc, num x, num y, num z, num endspeed, num priority, num preempting)
Deprecated, use Process Flow instead
Description
This command is deprecated. Use Process Flow instead.

 This command creates a task sequence for the object specified by dispatcher that causes it to travel to the point specified by xlox, y, and z. If relativeloc is 1, the specified point is relative to the origin of dispatcher. If relativeloc is 0, the specified point is the exact point in the model that dispatcher will try to travel to. It will travel until its front edge reaches the specified point. This task sequence will be given a priority of priority and a preempting value of preempting. The possible values for preempting are:

 0 - PREEMPT_NOT
1 - PREEMPT_ONLY
2 - PREEMPT_AND_ABORT_ACTIVE
3 - PREEMPT_AND_ABORT_ALL
Example
createtraveltoloctask(current.centerObjects[1], 1, 5.15, 2.5, 0, 0, 1, PREEMPT_NOT);

Deprecated, use Process Flow instead
Description
This command is deprecated. Use Process Flow instead.

 This command creates a task sequence for the object specified by dispatcher that causes it to unload flowitem into the object specified by destination. The object will not travel to the location before unloading. This task sequence will be given a priority of priority and a preempting value of preempting. The possible values for preempting are:

 0 - PREEMPT_NOT
1 - PREEMPT_ONLY
2 - PREEMPT_AND_ABORT_ACTIVE

createuserlibrary ()
Description
For developer use. This command creates a new user library
Example
createuserlibrary();
createview (str viewpath[, str objectfocus, str viewfocus])
Description
For developer use. This command creates a new GUI window in the active node of the views tree. This window is a copy of the window whose path is given in viewpath. The window will have an object focus of objectfocus and a view focus of viewfocus. Objectfocus and viewfocus are generally the same for most GUI windows. They should be the path of the node that this GUI window is representing.
Example
createview("VIEW:/standardviews/other/FindReplace","MAIN:/project/model/Tools/precision","MAIN:/project/model/Tools/precision");

 This creates the Find Replace GUI.
createwaittask (obj taskexecuter, num state, num priority, num preempting)
Deprecated, use Process Flow instead
Description
This command is deprecated. Use Process Flow instead.

 This command creates a task sequence on the object specified as dispatcher that causes the object to not perform new task sequences that it is given until it has been released. The object can be released with the endwaittask() command. The object will be in the state specified by state while it is waiting. For a list of possible states, see setstate() command. This task sequence will be given a priority of priority and a preempting value of preempting. The possible values for preempting are:

 0 - PREEMPT_NOT
1 - PREEMPT_ONLY
2 - PREEMPT_AND_ABORT_ACTIVE
3 - PREEMPT_AND_ABORT_ALL

cubemap (int cmd, int FACEa, int FACEb, int FACEc, int FACEd, int FACEe, int FACEf)
Attaches 2D images to vertices of a 3D model
Description
This command can be used to attach 2D images to vertices of a 3D model and the texture image is wallpapered onto the geometry of the 3D model. The six faces can be defined by FACEa, FACEb, FACEc, FACEd, FACEe, and FACEf. We can directly use the number of the reference texture after importing into media files. The parameter cmd will take the following values whenever writing OpenGL call sequences.

 1- CUBEMAP_INIT : To initialises the texture if nothing defined earlier
2- CUBEMAP_BEGIN : Enables texture generation and begin map
3- CUBEMAP_END : Disable texture generation and end map
4- CUBEMAP_SHUT : Delete map
Example
cubemap(2, 39,39,39,39,39,39);
current <no parentheses>
Description
This command is deprecated. This should not be used as a special command with the setcurrent command anymore. Instead, declare a treenode variable type as current, then use current in your code as any other variable type.
Example
treenode current = model().subnodes[3];
pt(current.name);

 This sets the object that is ranked 3 in the model to current and prints its name to the output console.
currentfile ()
Gets the path to the currently open model
Description
Returns the path of the currently open model.
Example
currentfile();
cursorinfo (obj/num view, num operation, num x/y/z, num pos/move)
Description
For developer use. This command represents a lot of functionality wrapped up into one command. It is a way of getting information regarding the position/state of the mouse for a window control.

view: the associated view, such as an ortho or planar view. This can also be an HWND (stored in a double).

operation: the type of operation you want to do:
    1 - gets x or y positions of the cursor in a planar view
    2 - get orthographic or perspective view coordinates
    3 - get current mouse button state.
             return value:
             0 : no buttons down
             1 : left down
             2 : right down
             3 : right and left down
             4 : double left click
    4 - update the cursor position
    5 - gets x or y positions of the cursor relative to the view
    6 - gets x or y positions of the cursor in screen coordinates
    7 - sets the x or y position of the cursor

xyz: 1(x), 2(y), or 3(z); not used for operation 3. For operation 4, if xyz=1, the cursor position will be updated with objects being drawing, if xyz=2 it will be updated with only the floor drawn.

pos/move: 1(pos) or 2(move); 1 gets absolute mouse position, and 2 gets the change since last update. only used for operations 1-2.

 The best way to test this functionality out is just by trial and error. Add an OnMouseMove attribute to the ortho view (make sure you rebind the view's attributes after you've added it: Build|Rebind Object Attributes), then print information to the output console.
Example
cursorinfo(c,2,1,1)
daemonstate (num thing)
Description
For developer use.

Returns the stats of:
1 - clock
2 - flythrough
3 - ticker
Example
daemonstate(1)
dataplot (obj tree, num type, num action, num x, num y, num z)
Description
For developer use. This command lets you create, reset or add data to a histogram, x/y chart, or a data series. The first three parameters define the associated node in the tree as well as the operation to do. The last three parameters, x,y and z, define the appropriate data for the operation. The first parameter should be the main node in the tree that holds the graph/histo data. The second parameter should be either 1, 2, or 3, and defines the type of data that the node holds. 1 means graphx data. For this data type the node contains a list of sub-nodes, and each sub-node contains a number that is a unique point in a data series. 2 means graphxy. For this data type, the node again contains a list of sub-nodes but this time the sub-nodes are paired together as x/y pairs. Nodes ranked 1 and 2 hold the x and y values for one data point, nodes 3 and 4 hold x and values for the next data point, etc. A type parameter of 3 means histo data. Here the node holds data associated with a histogram. The action parameter should be either 1, 2, or 3, and defines the action that you want to do. 1 means a create operation. This is only needed for histogram type data, as it needs to set up the node's sub-tree structure. To create a histogram plot, pass the minimum value for the histogram as the x parameter, the maximum value of the histogram as the y value, and the number of divisions, or buckets, as the z parameter. An action parameter value of 2 means you want to reset the data. This will clear the content of the node for graphx or graphxy data, and will reset the histogram values for histogram data. An action parameter value of 3 means you want to add a data point. For graphx and histo data, pass the data point as the x parameter. For graphxy data, pass the as the x and y paramters. In summary: Type: 1-graphx/2-graphxy/3-histo.
Action: 1-create (only needed for histo data)/2-reset/3-add point.
Data: x,y are data points [histo create: x=start, y=end, z=nr of divisions].
Example
dataplot(stats_contentgraph(model.find("Processor2")),2,3,8.6,5,0); This adds a point to Processor2's content graph for time 8.6 and content 5. This example is only for demonstration purposes. You should never need to do this since the Processor automatically maintains its content graph.
days (num days)
Gets the number of model time units in the give number of days
Description
Return the number of model time units in the given number of days.
Example
days(3)
dbchangetable (str tablename)
Open the table tablename in the ODBC database
Description
This command opens the table in the database called tablename. If the database is open in SQL mode, this command does nothing. The table that was open when this command was called will be closed. Only the new table can be read. This allows the user to read from multiple tables in Table mode without having to close and reopen the entire database.
Example
dbchangetable("Inventory");
This closes the currently open table and opens a table called Inventory.
dbclose ()
Closes the currently open ODBC database
Description
This command closes the currently open ODBC database. Only one database can be open at a time. If this command is called before dbopen(), it has no effect. If used after an SQL "INSERT" command it gives an error message. First use a normal "SELECT" statement before calling dbclose().
Example
if (current.donegatheringdata == 1)
dbclose();

 If the label donegatheringdata on current is set to 1, the current database is closed.
dbexportnode (obj tablenode, num startrow, num startcol, num numrows, num numcols)

dbgetfieldname (num column)
Gets the field name of the open ODBC database
Description
This command returns the name of the field or column specified by fieldnum in the currently open ODBC database. It returns an empty string if there is no database currently open. If the user specifies a field number that does not exist, an exception occurs.
Example
string ColName = dbgetfieldname(1);

 This sets ColName to the name of the first column in the current database.
dbgetmetrics ()
Gets the table dimensions of the open ODBC database
Description
Get the table dimensions of the open ODBC database
Example
dbgetmetrics()
dbgetmode ()
Gets the current mode of the open ODBC database
Description

 If the database is open, ColName is set to the name of the first column in the database.
dbgetnumcols ()
Gets the number of columns of the open ODBC database
Description
This command returns the number of columns in the currently open ODBC database. If there is no database open, it returns 0.
Example
for (int x=1; x<=dbgetnumcols(); x++)
Table("MyTable")[1][x] = stringtonum(dbgettablecell(1,x));

 This copies the values from a column in the database to a column in a GlobalTable.
dbgetnumrows ()
Gets the number of rows of the open ODBC database
Description
This command returns the number of rows in the currently open ODBC database. If there is no database open, it returns 0.
Example
for (int x=1; x<=dbgetnumrows(); x++)
Table("MyTable")[x][1] = stringtonum(dbgettablecell(x,1));

 This copies the values from a row in the database to a row in a GlobalTable.
dbgettablecell (num row, num col)
Gets the string associated with row, col of the open ODBC database
Description
This command returns a string containing the information that is found in the cell specified by row and col in the currently open ODBC database. If there is no database open, this function returns a null string (a value of 0).
Example
double tablevalue = stringtonum(dbgettablecell(1,1));

 This sets tablevalue to the number that is stored in the first row and first column of the database.
dbgettablenum (num row, num col)
Gets the number of the row,col of the current open ODBC table
Description
Returns the number found in the specified row and col of the current database table.
Example
double val = dbgettablenum(2,3);
dbgettablestr (num row, num col)
Gets the string of the row,col of the currently open ODBC table
Description
Returns the string found in the specified row and col of the current database table.
Note: if used in FlexScript only fields it will return a number which must be converted to a string explicitly using tostring().
Example
string val = dbgettablenum(2,3);
dbimportnode (obj tablenode, num startrow, num startcol, num numrows, num numcols)

to import.
Example
dbimportnode("MyTable4",2,2,3,3);
dbopen (str databasename, str command {SQL string or Tablename}, num usetable [, num showlogin])
Opens an ODBC database
Description
This command attempts to open an ODBC database. Returns a 1 for success, 0 otherwise. The database must have an ODBC alias (or Data Source Name DSN) defined before it is opened. This is done using the "Data Sources" option in the Windows Control Panel. The alias name is passed to the command as databasename, the database file name should not be passed. Databases can be opened in two different modes. These modes have slightly different behavior and available commands. The two modes are SQL mode and Table mode. If the parameter tablemode is 1, then the database will be opened in Table mode, and command should be the name of the table in the database to open. If the table is opened successfully, the entire table will be available to read. Individual cells can be edited in Table mode. No SQL commands should be called if the database is in Table mode. If tablemode is 0, then the database will be open in SQL mode and command should be the initial SQL query. If the query executes successfully, only the result of the query will available to read. Individual cells cannot be edited in SQL mode. However, SQL update queries can be called once the database is open. If showlogin is 1 then the standard login prompt (username/password) will be shown before the connection to the database is made.
Example
dbopen("itemdrive","timetable",1);

 This opens a database with the alias "itemdrive" and opens the table called "timetable" in Table mode.

 dbopen("warehouse","select * from inventory",0);

 This opens a database with the alias "warehouse" and performs a SQL query on it. The database is open in SQL mode.
dbsettablecell (num row, num col, str value)
Sets the value for row, cell of the open ODBC database
Description
This command sets the value of the cell specified by row and col in the currently open ODBC database to value. If the database is open in SQL mode, this command does nothing. If the database alias is set to be read-only, this command will cause an exception. Aliases are set to read-only in the "Data Sources" option of the Windows Control Panel. If a number value needs to be passed to the function, the strintonum() command should be used.
Example
for (int x=1; x<= model().subnodes.length; x++)
dbsettablecell(x,1,model().subnodes[x].name);

 This places the names of all of the objects in the model into the first column of the current database.
dbsettablenum (num row, num col, num val)
Sets the number of row,col of the currently open ODBC table
Description
Sets the number found in the specified row and col of the current database table to the given value.
Example
dbsettablenum(2,3,56.5);
dbsettablestr (num row, num col, str val)
Sets the string of the row,col of the currently open ODBC table
Description
Sets the string found in the specified row and col of the current database table to the given value.
Example
dbgettablestr(1,1,"John");
dbsqlquery (str query[, num forwardOnlyCursor])
Perform an SQL query on the open ODBC database
Description
This command performs the SQL query specified by query on the currently open database. The result becomes the current table. If the database is in Table mode, this command does nothing. If the query returns a table, that table can be read using the dbgettablecell() command. If the query performed an update, the dbgettablecell() command will cause an exception to occur.
After performing UPDATE statements with this command, a SELECT should be called immediately following, as there is no table returned by an UPDATE. This command is only usable in SQL mode. If forwardOnlyCursor is 1, then it will assume the result is a forward-only-cursor result. For forward-only cursors you cannot use dbgetnumrows(). Instead, after the call to dbsqlquery(), you call dbnextrow(). This command will return the activated row. It will return -1 once it hits the end of the table.
Example
dbsqlquery("select processtime from timetable where type='1'");

 This returns a new table based on the SQL query passed.

 dbsqlquery("update timetable set processtime=type*2");

 This updates the database based on the query passed.
dbusername (str username, str password)
Sets the username and password used to access an ODBC database with dbopen()
Description
This command sets the username and password that will be used to access a database when dbopen() is called next. This allows a model builder to use the login parameters required by a database, without having to use the username/password prompt that dbopen() provides. The username and password set by this command will be used every time dbopen() is called until they are changed by calling dbusername() again. It is acceptable to set either the username, password or both to an empty string.
Example
dbusername("user1","abc123XYZ");

This sets the username to "user1" and the password to "abc123XYZ". These values will be used to access a database the next time dbopen() is called.

 dbusername("","");

This clears out the last set username and password. The next time dbopen() is called, the database will be accessed without a username or password.
dbviewtable ()
Opens a read only dialog box displaying the currently loaded ODBC table
Description
Opens a dialog box displaying the currently loaded database table. The table cannot be edited from this dialog.

defaultdragconnection (obj fromobject, obj toobject, char characterpressed)
Deprecated, use contextdragconnection()
Description
This command is deprecated. Use contextdragconnection() instead.

 Either connects or disconnects ports between fromobject and toobject according to the specified characterpressed. This command mimics the keyboard and mouse combinations used to connect/disconnect object ports. For instance an 'A' would be as if the letter "A" were held down on the keyboard while click-dragging from the fromobject to the toobject. For 'A' and 'Q' it connects and disconnects output ports to input ports. For 'S' and 'W' it connects and disconnects central ports. Can only be used in C++, not flexscript.
Example
defaultdragconnection(model().subnodes[count], model().subnodes[2], 'A')

 Deletes the specified label from the node called "labels" on the specified object.
The specified label can either be the labelname as a string or the label's rank as a number.
If the label does not exist in that node, this command does nothing.
Example
dellabel(current,"MyLabel")
dempirical (str/node/num table[, num stream])
Returns a random sample from a discrete empirical distribution
Description
A discrete empirical distribution.

 The table referenced must contain a list of values and probability percentages associated with each of the values. Probability percentages must be entered in column 1 starting with row 1 of the table, and their associated values are entered in column 2. The table may have as many rows as needed to define as many values as desired. The percents are entered as numbers between 0 and 100, and should add up to a total of 100 percent; otherwise any values defined after a cumulative percentage of 100 is reached will never be returned.

 A detailed description of the three empirical distributions used in FlexSim and their differences is included with the cempirical() command.
Example
int ptype = dempirical("prodtypes", 5);

Assigns a value to the ptype variable using a discrete empirical distribution defined in a global table named "prodtypes" using random number stream 5.

dempirical(current.labels["route"], 5);

Description
Destroys events associated with the given object. The first parameter, object, is the only required parameter. Other parameters are optional and provide a filter for choosing which events to destroy, as follows:

 time: If greater than or equal to the time that that the command is called, this parameter will filter events by their time. If the event's time is not equal to the time passed in, then the event will not be destroyed. Pass -1 if you don't want this as a filter.

 code: If greater than 0, this parameter filters events by their event code. If the event's code is not equal to the code passed in, the event will not be destroyed.

 data: If not NULL, this parameter filters events by the data string associated with the event. If the event's data string is not equal to the string passed in, the event will not be destroyed.

 involved: If not NULL, this parameter filters events by their involved node or object. If the event's involved node is not equal to the node passed in, the event will not be destroyed.

draw3dtext (str text[, num asBitmap])
Draws text in a 3d view
Description
This command is similar to drawtext(), but can only be used in a 3D view, and its parameter set is stripped down to provide direct access to the text rendering procedure. Whereas drawtext() does some automatic scaling based on the current object, as well as some OpenGL state changes, etc., draw3dtext() calls the text drawing procedure directly, so any positioning, scaling, color settings, etc., should be done with OpenGL commands, i.e. glTranslated(), glScaled(), glColor3d(), etc.
Example
draw3dtext(current.name);
drawbox (num x, num y, num z, num sx, num sy, num sz, num glbegin)
Draws a simple box
Description
Draws a simple box. If glbegin is 1, then it will call glBegin before drawing. This command is a shortcut way to draw an OpenGL type cube that allows more control over lighting, coloring, and texturing than the drawcube() command.
Example
drawbox(5,0,0, 2,1,3, 1);
drawcolumn (num x, num y, num z, num totalsides, num baseradius, num topradius, num height, num rx, num ry, num rz, num red {0-255}, num green {0-255}, num blue {0-255} [, num opacity {0-1}, num textureindex, num textureXrepeat, num textureYrepeat])
Draws a 3D column
Description
A very versatile command that can draw anything with multiple sides and a height such as a square, a pentagon, a pyramid, and even a cylinder (if the total number of sides is large).

Draws a column with its origin (center of base) positioned at x, y, z. The column is then defined by the number of sides, a base radius, a top radius, and a height. The column can be rotated in degrees about each axis with rx, ry, rz. The color is defined by the red, green, blue color components ranging from 0 to 255.

An optional opacity parameter will change the column from clear (0) to opaque (1). If a valid textureindex number is entered, then the associated image will be repeated textureXrepeat and textureYrepeat times on each face of the column.

The location, size and rotation of the column are by default relative to the object it is drawn on. The parameters shown in brackets [ ] must ALL be used or ALL not used. The textureindex is a numeric value that can be learned using the gettextureindex() command or through the Tools | Media Files menu.
Example
drawcolumn(0,0,0, 5 ,4,2, 6 ,0,0,0, 175,175,175, .6, 3, 5,1);
drawcube (num x, num y, num z, num sx, num sy, num sz, num rx, num ry, num rz, num red {0-255}, num green {0-255}, num blue {0-255} [, num opacity {0-1}, num textureindex, num textureXrepeat, num textureYrepeat])
Draws a 3D cube
Description
Draws a cube with its origin (bottom left corner) positioned at x, y, z. Its length, width, and height is defined by sx, sy, and sz respectively. It can be rotated in degrees about the x, y, and z axis by rx, ry, and rz. The color is defined by the red, green, blue color components ranging from 0 to 255.

An optional opacity parameter will change the cube from clear (0) to opaque (1). If a valid textureindex number is entered, then the associated image will be repeated textureXrepeat and textureYrepeat times on each face of the cube.

The location, size and rotation of the cube are by default relative to the object it is drawn on. The optional parameters shown in brackets [ ] must ALL be used or ALL not used. The textureindex is a numeric value that can be learned using the gettextureindex() command or through the Tools | Media Files menu.
Example
drawcube(0,0,0, 5,3,2, 0,0,0, 175,175,175, .6, 3, 1,1);
drawcylinder (num x, num y, num z, num baseradius, num topradius, num height, num rx, num ry, num rz, num red {0-255}, num green {0-255}, num blue {0-255} [, num opacity {0-1}, num textureindex])
Draws a 3D clyinder
Description
This command draws a hollow cylinder with its origin (center of base) positioned at x, y, z. The cylinder's dimensions are defined by a base radius, a top radius and a height. Use the drawdisk() command to cap off the ends of the cylinder. The cylinder can be rotated in degrees about the x, y, and z axis by rx, ry, and rz. The color is defined by the red, green, blue color components ranging from 0 to 255.

An optional opacity parameter will change the cylinder from clear (0) to opaque (1). If a valid textureindex number is entered, then the associated image will be used as texturing around the outside circumference of the cylinder.

The location, size and rotation of the cylinder are by default relative to the object it is drawn on. The optional parameters shown in brackets [ ] must ALL be used or ALL not used. The textureindex is a numeric value that can be learned using the gettextureindex() command or through the Tools | Media Files menu.
Example
drawcylinder(0,0,0, 1,1, 5, 0,0,0, 175,175,175, .6,3);
drawdisk (num x, num y, num z, num innerradius, num outerradius, num startangle, num sweepangle, num rx, num ry, num rz, num red {0-255}, num green {0-255}, num blue {0-255} [, num opacity {0-1}, num textureindex])
Draw a 3D disk
Description
Draws a flat planar disk with its origin (center of radius) positioned at x, y, z. The disk's dimensions are defined by an inner radius, an outer radius, a start angle, and a sweep angle. A sweep angle of 360 makes a complete circle. An innerradius greater than 0 will create a disk with a hole in the middle of it. The disk can be rotated in degrees about the x, y, and z axis by rx, ry, and rz. The color is defined by the red, green, blue color components ranging from 0 to 255.

An optional opacity parameter will change the disk from clear (0) to opaque (1). If a valid textureindex number is entered, then the associated image will be used as texturing across the face of the disk.

The location, size and rotation of the disk are by default relative to the object it is drawn on. The optional parameters shown in brackets [ ] must ALL be used or ALL not used. The textureindex is a numeric value that can be learned using the gettextureindex() command or through the Tools | Media Files menu.
Example
drawdisk(0,0,0, .5,2, 90,270, 0,0,0, 175,175,175, 1,3);
drawflattext (str text)
Description
This command can only be used in a 3D view. It draws a texture-mapped text string. This uses the same functionality that draws the names and stats below objects. If scaled correctly, it draws a very crisp, readable text. Use this in conjunction with setdrawnamefunction() to customize the data that is shown in the box below objects. Unlike drawtext(), this command's parameter set is much more stripped down, so you should use gl commands (i.e. fglTranslate(), fglScale(), fglColor(), etc.) to set up the location, size, and render settings before drawing the text.
Example
Add the following code to an object's Custom Draw Code trigger: 

if(!param(2)) {
	setdrawnamefunction(80, 15, c, param(1), 1);
} else {
	fglTranslate(-40, -15, 0);
	drawflattext("Hello World");
}
This will draw the text Hello World in the display box below the object
drawfont (num font)
Specifies the font to be used with drawtext()
Description
Call before drawtext, to define font to be drawn. After drawtext is called, the font will be reset to default. There are currently 12 font types (numbers 0 through 11).
Example
drawfont(2)
drawimage (obj view, str imagepath, num x, num y, num width, num height, num scaling)
Draws an image
Description
Draws the image at imagepath in the view. The scaling value specifies how the image will be positioned and scaled.
NO_SCALE (or 0): Draws the image at location x,y with the width and height being based on the size of the image.
SCALE_DOWN: Draws the image centered in the rectangle created by x,y,width,height and scales the image proportionally down to fit if necessary.
SCALE_UP_DOWN: Draws the image centered in the rectangle created by x,y,width, height and scales the image proportionally up or down to fit.
SCALE_INDEPENDENT: Draws the image at x,y with the size of width and height.
Example
drawimage(c, "buttons\\visible_eye.png", 0, 10, 0, 0, 0);

Example
if(current.stats.output >= 5000) endreplication(1);
endwaittask (obj taskexecuter)
Deprecated, use Process Flow or freeoperators()
Description
This command is deprecated. Use Process Flow instead or the freeoperators() command instead.

 This command releases the object specified as dispatcher from a wait task issued by the createwaittask(). Once the object is released, it will return to the state that it was previously in, and it will begin to perform any task sequences that are in its tasksequence queue.

Example
erlang (num location, num scale, num shape[, num stream])
Returns a random sample from an erlang distribution
Description
erlang( γ, β, m, stream ) is a non-negative continuous probability distribution.

Inputs:
γ is the location parameter ∈ ( - ∞, ∞ )
β is the scale parameter ( β > 0 )
m is the shape parameter ∈ {1, 2, ... }
stream is a reference to one of FlexSim's random number streams {0,1,2,...}

Outputs:
range = ( γ , ∞ )
mean = γ + mβ
variance = mβ²

Possible Applications:
Used to model the time to complete some task such as assembly, customer service and machine repair.

Comments:
When γ = 0, this distribution is known as the m-Erlang(β) distribution.
The exponential( γ, β ) and erlang( γ, β, 1 ) distributions are the same.
For a positive integer m, the gamma( γ, β, m ) and erlang( γ, β, m ) distributions are the same.
Example
double servicetime = erlang(60, 2, 4, 5);

The servicetime variable is set equal to a erlang distribution with a location parameter of 60, a scale parameter of 2, a shape parameter of 4, using random stream number 5. The mean is 100 + (2*4) = 108.
evaluatepullcriteria (obj fixedresource, obj item, num portnr[, num bypassflags])
Causes the FixedResource object to re-fire its pull requirement
Description
Tells the FixedResource to evaluate its pull requirement for the passed item that is in the object through the input port portnr. This command returns the value returned by the pull requirement field if the item can be pulled. If the item cannot be pulled for any of various reasons (such as closed ports or the item not being released), then this command returns 0. The bypassflags parameter is a bitwise combination of macros that start with BYPASS_ to specify certain criteria to ignore in determining item availability.
Example
evaluatepullcriteria(current, item, 1); // See also Pull Best Item picklist option
eventcode <no parentheses>
Description
For developer use. This command returns the number value that was passed to the createevent() command as code. It is only used in the OnTimerEvent function of the library objects. It is generally used to identify the type of event that is occurring. This command should not have parentheses when it is called. See also createevent() and eventdata.
Example
if (eventcode == EVENT_OPENINPUTS)
thisobjectdata->openinputs();

 This calls a method called openinputs() on the object referenced by thisobjectdata if the value EVENT_OPENINPUTS was passed to the createevent() function.
eventdata <no parentheses>
Description
For developer use. This command returns the string value that was passed to the createevent() command as data. It is only used in the OnTimerEvent function of the library objects. Generally, it is used as a description to the user of the type of event that is occurring. It is not generally used in the execution of the OnTimerEvent function, for speed reasons. This command should not have parentheses when it is called. See also createevent() and eventcode.
Example
if (comparetext(eventdata,"openinputs"))
{
thisobjectdata->openinputs();
}

 This calls a method called openinputs on the object referenced by thisobjectdata if the string value passed to createevent() is equal to "openinputs".
eventget (num index, num thing)
An event attribute for the event at index
Description
Returns an event attribute at the specified index in MAIN:/project/exec/events.
thing can be:
1 = client
2 = time
3 = code
4 = data
5 = involved
6 = event node
Example
eventget(2,3)
eventlisten (obj object, str eventName, node relayNode[, num flags, par1, par2, ... par10])
Description
This command will create a listening mechanism where whenever the defined event is called on object, relayNode will also be executed. flags is a bitwise mask of one of the following values:
EVENT_PRE_LISTEN: The listening function will be called before theNode is called.
EVENT_LISTEN: (default) The listening function will be called after theNode is called.
EVENT_PERSIST: The listener will persist across model resets.
EVENT_PASS_THROUGH_PARAMS: When theNode is called, the parameters passed into the event will also be "passed through" into the listening node. In this case, par1, par2, etc. are not used.
EVENT_LISTEN_ONCE: The listening mechanism will automatically be removed after the first event firing.
When the listening node is called, if it returns EVENT_STOP_LISTENING, the listener mechanism will be removed and the listening node will no longer be called. The return value is a reference to a node associated with the listening. If this node is later deleted, the listening mechanism will stop.

 To get a list of the events that can be listened to on an object, call function_s(object, "enumerateEvents", destNode). The object will dump a table onto destNode that contains information on all the events that can be listened to on the object.

 Some events may have "requirements". This means that in order to properly bind to the event, you have to pass additional parameters in. The enumeration table will give information on the number of requirements and their names. When requirements are needed they displace and shift par1, par2, etc. For example, if an event has 2 requirements, these requirements will take up par1 and par2 of the eventlisten() call, and par3 will then become param(1) in relayNode's code.
Example
eventlisten(current, "OnEntry", current.entrylistener);
eventloginfo (num operation, num n1)
Description
For developer use. Returns a string value describing something related to the Event Log.

 Operations:
ELI_GET_OBJECTPATH 1 - returns the path of the object at index n1 from the objectpaths array.
ELI_GET_INVOLVEDPATH 2 - returns the path of the object at index n1 from the involvedpaths array.
ELI_GET_OTHERPATH 3 - returns the path of the object at index n1 from the otherpaths array.
ELI_EVENTTYPE_NAME 4 - returns the name of the eventtype at index n1 from the eventtypes array.
ELI_LOGGEDEVENTTYPE_NAME 5 - returns the name of the logged eventtype at index n1 from the loggedeventtypes array.

 Other operations relating to the Event Log that return number values can be accessed using the applicationcommand() function:
"seteventlogging" - enables or disables logging for eventtype n1.
"geteventlogging" - returns whether logging is enabled for eventtype n1.
"getobjectpathslistsize" - returns the size of the objectpaths array.

excelimportnode(so(),1,1,5,3);
excelimporttable (str/node/num table, num startrow, num startcol, num numrows, num numcols)
Imports data from the currently open Excel workbook to a table in FlexSim
Description
Imports data from Excel to a table in FlexSim. The table may be referenced by the name of a GlobalTable or by using a treenode reference to a table node. The type of data (string or number) to be exported is determined by the datatype of the cells in the FlexSim table. The user specifies the starting row and column number in Excel, and the total number of rows and columns to export.
Example
excelimporttable("MyTable",1,1,5,3);
excellaunch ([str launchdir])
Launch Microsoft Excel
Description
This command opens Microsoft Excel so that it can be accessed by FlexSim. If launchdir is not specified, the path defined in Tools|Excel...|Global Settings will be used. Otherwise, the launchdir must be an accurate path to the location on the hard drive where EXCEL.EXE is located. It is typically something like "C:/Program Files/Microsoft Office/Office10," but may be different depending on the version of Excel installed. It is generally not required to launch Excel before communicating with it. However, if FlexSim is set to communicate with Excel via DDE (by calling maintenance(1000,1), this is not the default behavior) Excel must be running before any communication can be performed. If excellaunch() is called at the beginning of communication, excelquit() must also be called before the user opens a new model, compiles the current model or closes FlexSim.
Example
excellaunch(" C:/Program Files/Microsoft Office/Office10");
excelopen("C:/mybook.xls");
excelsetsheet("Sheet1");
double thenum = excelreadnum(1,1);
excelclose(true);
excelquit();

 This starts Excel, opens a workbook called "mybook," stores a value read from row 1, column 1 from that workbook, then closes the file and Excel.
excelmacro (str macro)
Deprecated
Description
This command is deprecated. This command allows the user to send an Excel 4.0 macro command to Excel. This language is no longer maintained by Microsoft and may be removed from future versions of Excel.
Example
excelmacro("select(\"r1c1:r5c5\")");

 This selects the section of the workbook beginning at row 1, column 1 to row 5, column 5.
excelmultitableimport ()
Starts the automatic importing of data from Excel to FlexSim tables
Description
Starts the automatic importing of data from Excel sheets to FlexSim tables as setup in the Tools | Excel... | Multiple Table Import window.
Example
excelmultitableimport()
excelopen (str workbook)
Open the Excel workbook
Description
This command opens the file called workbook in Excel. Only one workbook can be open at a time. The user must call excelclose() before trying to open another workbook, opening a new model, compiling the current model, or closing FlexSim. Before reading from the open file, excelsetsheet() must also be called.
Example
excelopen("mydata.xls");
excelsetsheet("Sheet1");
double myvalue = excelreadnum(1,2);
excelclose(0);

 This first creates a link between FlexSim and an Excel workbook called "mydata.xls", then sets the active sheet in the workbook to "Sheet1", sets a local variable called myvalue to the number read from row 1 column 2, then closes the workbook without saving.
excelquit ()
Close Microsoft Excel
Description
This command closes Microsoft Excel if it is open. After this command is called, no other commands to Excel should be called. Any Excel files that were open should be closed before this command is called. You may get an Excel prompt to save changes to any workbooks that were left open. Use excelclose() to avoid this. This command must be called if excellaunch() was called previously.
Example
see excellaunch();
excelrangeread (str rangename[treenode target], num row, num col[, num numRows, num numCols, num flags])
Reads an Excel range and dumps it to a treenode
Description
This function is overloaded so that it has two functions depending on which arguments you pass in. The first (where you pass in a string) is deprecated. Use excelrangereadnum() and excelrangereadstr() instead.

The second (where you pass in a treenode) will read a range in Excel and assign all of the data in that range to the target treenode. If the treenode has bundle data, the excel data will be set on the bundle. Otherwise, subnodes will be inserted under the target treenode that will have the Excel data set on them as either string or number data, in the same format as Global Tables.

The origin of the range is specified by the row and col passed in, and the second pair of numbers will specify the size of the range. If 0 is passed in for any one of these, Flexsim will automatically choose the boundary in that direction of the Excel range that has data.

Flags can be passed in to change exactly what is read from Excel. Those flags are EXCEL_DATA_AUTOMATIC, EXCEL_DATA_NUMBER, EXCEL_DATA_STRING, EXCEL_DATE_AS_NUM, EXCEL_USE_COLUMNHEADERS and EXCEL_USE_ROWHEADERS.

EXCEL_DATA_AUTOMATIC will assign string or number data based on what the datatype of the Excel cell is. This is the default behavior.

EXCEL_DATA_NUMBER will force all Excel data to be read as a number.

EXCEL_DATA_STRING will force all Excel data to be read as a string.

EXCEL_DATE_AS_NUM will read any Excel dates as numbers readable by Flexsim as dates. Otherwise, the data will come in as a string.

EXCEL_USE_COLUMNHEADERS will take the first row of data and use it as names for the table columns instead of data.

EXCEL_USE_ROWHEADERS will take the first column of data and use it as names for the table rows instead of data.

Example
treenode myTable = node ("Tools/GlobalTables/GlobalTable1>variables/data", model());

excelrangeread(myTable, 1, 1, 5, 0, EXCEL_DATA_AUTOMATIC | EXCEL_USE_COLUMNHEADERS);

This will read data from the active sheet starting at cell A1. It will read the first five rows, and read as many columns as have data in them. The first row will be used as names for the columns of the Global Table we're writing to. Therefore, if the Excel sheet has 10 columns with data in them, a total of 40 nodes will be inserted under the data variable of the Global Table. Each of those nodes will have the datatype of their corresponding Excel cell.
excelrangereadnum (str rangename, num row, num column)
Read the numeric value from a cell of the specified range of the currently open Excel workbook
Description
Reads a numeric value from a cell defined by row and column in the specified named range. The upper-left cell of the range is row 1, column 1.
This command does nothing if FlexSim is set to communicate with Excel using DDE (by calling maintenance(1000,1), not FlexSim's default setting).
Example
excelreadnum("MyRange",5,1)
excelrangereadstr (str rangename, num row, num column [, num rowchar, num colchar])
Read the text value from a cell of the specified range of the currently open Excel workbook
Description
Reads a text value from a cell defined by row and column in the specified named range. The upper-left cell of the range is row 1, column 1.
This command does nothing if FlexSim is set to communicate with Excel using DDE (by calling maintenance(1000,1), not FlexSim's default setting).
Example
excelreadstr("MyRange",5,1)
excelrangewrite (str rangename[treenode source], str value[num row], num row[num col], num col[num flags])
Reads data under a treenode and writes it to the active Excel sheet
Description
This function is overloaded so that it has two functions depending on which arguments you pass in. The first(where you pass in a string) is deprecated. Use excelrangewritenum() and excelrangewritestr() instead.

The second (where you pass in a treenode) will write all the of the data under a treenode to the active Excel sheet. If the treenode has bundle data, this will read the bundle and write it to the sheet, otherwise it will look for child nodes with data on them, like a Global Table. The row and col passed in here specify where on the Excel sheet to begin writing the data. All of the data on the source node will always be written. Flags can be passed in to change the use of headers. Those flags are EXCEL_USE_COLUMNHEADERS and EXCEL_USE_ROWHEADERS.

EXCEL_USE_COLUMNHEADERS will write any existing column headers as a separate row in the Excel table.

EXCEL_USE_ROWHEADERS will write any existing row headers as a separate column in the Excel table.
Example
treenode myTable = node ("Tools/GlobalTables/GlobalTable1>variables/data", model());

excelrangewrite(myTable, 1, 1, EXCEL_USE_ROWHEADERS | EXCEL_USE_COLUMNHEADERS);

This will take all of the data in GlobalTable1 and write it to the active Excel sheet, starting at cell A1. Before it writes any of the actual data, there will be a row of column headers and column of row headers.
excelrangewritenum (str rangename, num row, num column, num value)
Write the numeric value to a cell of the specified range of the currently open Excel workbook
Description
Writes a numeric value to a cell defined by row and column in the specified named range. The upper-left cell of the range is row 1, column 1.
This command does nothing if FlexSim is set to communicate with Excel using DDE (by calling maintenance(1000,1), not FlexSim's default setting). For writing a whole table of values to Excel, use excelrangewrite.
Example
excelwritenum("MyRange",5,1,99.87)
excelrangewritestr (str rangename, num row, num column, str value)
Write the string value to a cell of the specified range of the currently open Excel workbook
Description
Writes string value to a cell defined by row and column in the specified named range. The upper-left cell of the range is row 1, column 1.
This command does nothing if FlexSim is set to communicate with Excel using DDE (by calling maintenance(1000,1), not FlexSim's default setting). For writing a whole table of values to Excel, use excelrangewrite.
Example
excelwritestr("MyRange",5,1,"My String")
excelread (num row, num col)
Deprecated, use excelreadnum(), excelreadstr() or excelreadcell()
Description
This command is deprecated. Use excelreadnum(), excelreadstr() or excelreadcell() instead.
Example
excelreadcell (num row, num col[, num flags])
Returns the value of a cell in the active worksheet as a variant
Description
Returns the value of a cell in the active worksheet as a variant. Flags can be specified to specify what exactly is returned from Excel. Those flags are EXCEL_DATA_NUMBER, EXCEL_DATA_STRING, and EXCEL_DATE_AS_NUM.

EXCEL_DATA_NUMBER will read the Excel data as a number.

EXCEL_DATA_STRING will read the Excel data as a string.

EXCEL_DATE_AS_NUM will interpret any Excel dates as a Flexsim readable date number.
Example
Variant value = excelreadcell(1, 5, EXCEL_DATA_NUMBER | EXCEL_DATE_AS_NUM);

This returns the value of the 5 column in the first row as a number. If it's a date, the number returned will be Flexsim readable as a date.
excelreadnum (num row, num column [, num rowchar, num colchar])
Read the numeric value from a cell of the active sheet of the currently open Excel workbook
Description
Reads a numeric value from a cell defined by row and column of the active sheet of the currently open Excel workbook.
Example

executefsfile (str filename, num direct)
Description
For developer use. Executes Flexscript code in a file. The specified file is loaded and its content is executed. The contents of the file are assumed to be valid Flexscript code. If direct is 0, then FlexSim's program directory will be concatenated onto the front of filename, otherwise filename will remain as it is.
Example
executefsfile("c:/myscript.fs",1)
executefsnode (node thenode, node c[, node i, node/num/str eventdata, int nobuild])
Execute a node as Flexscript
Description
Dynamically execute a node as Flexscript. If the node is not already Flexscript, the nobuild parameter should be 0. Used to parse string data into Flexscript to execute, such as from a global table or label. The c and i parameters can be accessed in the function as c and i. The eventdata parameter can be accessed as eventdata if it is a string or as eventcode (an integer) if it is a number. If eventdata is a node, it can be accessed using tonode(eventdata) in the function.
Example
executefsnode(current.labels["myFunc"],NULL,NULL,NULL,0)

 This executes the script on current's myFunc label, passing NULL into the function for c,i,and eventdata.
executestring (str thestring[, node c, node i, obj eventdata])
Executes a string as flexscript
Description
Executes the given string as flexscript. Parameters 2-4 are the same as executefsnode.
Example
executestring("profileevents()");
executesubflow (obj/str processFlow [, obj instanceObject, str startActivity, str finishActivity])
Description
Creates a token in a Process Flow Sub Flow which starts that sub flow. Once the created token hits a Finish activity it will return the value evaluted from the Return Value field.
instanceObject: If the instanceObject is specified then current may be used by the activities in the Sub Flow to get access to the instanceObject. This can be useful when multiple objects execute the same Sub Flow but require object specific data.
If no Start activity is specified, the activities in the Sub Flow will be searched and the first Start activity will be used.
If multiple Finish activities are contained in the Sub Flow, the return value will be evaluated from whichever Finish activity the token enters. However, if internal sub flows cause other tokens to enter a Finish activity, it may be necessary to specify the Finish activity name so the correct return value is evaluated.

NOTE: It is important that the activities used in the Sub Flow do not create delays or wait. If the token is interrupted by a delay or wait, the token will not arrive at the Finish activity when the executesubflow function finishes.
Example
return executesubflow("SubFlow1", processor);
executetablecell (str/node/num table, num row, num column)
Deprecated, use Table.executeCell() or the Table's [] operators
Description

Example
exp (num value)
Deprecated, use Math.exp()
Description
This command is deprecated. Use Math.exp() instead.

 Returns (e ^ value) where e is 2.7183.
Example
exponential (num location, num scale [, num stream])
Returns a random sample from an exponential distribution
Description
exponential( γ, β, stream) is a non-negative continuous probability distribution.

Inputs:
γ is the location parameter ∈ ( - ∞, ∞ )
β is the scale parameter ( 0, ∞ )
stream is a reference to one of FlexSim's random number streams {0,1,2,...}

Outputs:
range = ( γ, ∞ )
mean = γ + β
variance = β²

Possible Applications:
Often used to model the interarrival times of a continous stream of customers and/or customer orders into a system. It is also a popular distribution for modeling the time between failure of mechanical equipment.

Comments:
Variates less than the mean occur much more frequently than variates greater than the mean.
The exponential distribution is the only continuous distribution with the memoryless property of producing totally independent variates.
If the location parameter (γ) is set to zero, then β becomes the mean, and the distribution's variates will range between zero and infinity.
The exponential( γ, β ) and gamma( γ, β, 1 ) distributions are the same.
Example
exponential(0, 10, 5);

An exponential distribution with a location of 0 and a scale of 10 (mean = 10). FlexSim's random stream number 5 will be used to generate variates from the distribution.
exportdataset (node datatree, str filename, num format)

fastspline (obj spline, num perc [0-1])
Description
For developer use. Get a spline mapping from a cached spline. This command will set the values to be returned by subsequent calls to the splinex(), spliney(), splinez(), splinerx(), splinery(), splinerz(), splinelength(), splineposobject() commands. It will use the precalculated values for the spline object given in spline. The parameter perc is the position along the spline of interest.

For developer use. Set the OpenGL debug level. The higher the number, the more scrutiny is put on the system, and the more reporting is done. 0 is none, 3 is maximum.
Example
fgldebuglevel(3)
fglDisable (num setting)
Disables an OpenGL draw setting
Description
Disables an OpenGL draw setting. See glEnable() for list of draw settings. You can refer to standard OpenGL documentation for more information if needed.
Example
fglDisable(GL_LIGHTING);
fglEnable (num setting)
Enables an OpenGL draw setting
Description
Enables an OpenGL draw setting. Note that for optimization purposes, FlexSim's drawing engine does not automatically restore the enabled/disabled state of a given setting, so it is up to you, if you use this command, to restore the setting to its default after you have executed your drawing functionality. Failing to restore a setting to its default will result in weird rendering of other objects in the model.

Common OpenGL draw settings:
GL_LIGHTING
    Turns lighting on and off.
    Turn it on if polygons do not change color when they turn away from the viewer.
    Default: enabled.
GL_CULL_FACE
    Turns back-face culling on and off
    Turn it off if you want both sides (front and back) of all polygons drawn.
    Default: disabled.
GL_TEXTURE_2D
    Turns texturing on and off.
    Turn it off if a texture is being displayed and you don't want it there.
    Default: enabled.

You can refer to standard OpenGL documentation on glEnable() for more information if needed.
Example
fglEnable(GL_LIGHTING);
fglinfo (num operation, obj view)
Gets information about a 3D view's draw state
Description
This command gives you access to various information about the draw state of a 3d view. Logic/data that is performed/returned is based on the operation parameter, as follows:

FGL_INFO_SHADERTYPE - returns what part of the draw pass is happening, such as rendering the shadow map (SHADERTYPE_RENDER_SHADOWS), blurring the shadow map (SHADERTYPE_BLUR), or rendering the objects to the screen (SHADERTYPE_DEFAULT).

Example
/*do not draw this object when rendering the shadow map*/
if (fglinfo(FGL_INFO_SHADERTYPE, view) == SHADERTYPE_RENDER_SHADOWS)
    return 0;
fglLoadIdentity ()
Description
Loads the identity matrix into the current OpenGL drawing context, or in other words, replaces the current matrix with the identity matrix. A matrix is just a way to specify a whole bunch of n-dimensional transformations in one convenient package. Loading the identity matrix is simply a way of resetting things to the origin, so there's no rotation, translation or scaling. The default position is (0,0,0) and the default orientation is looking down the negative z-axis. You can refer to standard OpenGL documentation for more information if needed.
Example
fglLoadIdentity()
fglMatrixMode (num mode)
Specifies which matrix stack is the target for subsequent matrix operations
Description
Specifies which matrix stack is the target for subsequent matrix operations. A matrix is just a way to specify a whole bunch of n-dimensional transformations in one convenient package. Three values are accepted: GL_MODELVIEW, GL_PROJECTION, and GL_TEXTURE. The initial value is GL_MODELVIEW which is used when moving objects around the scene. You can refer to standard OpenGL documentation for more information if needed.
Example
fglMatrixMode(GL_MODELVIEW);
fglNormal (num x, num y, num z)
Sets the normal vector for shading subsequent vertices in OpenGL
Description
Sets the normal vector for shading subsequent vertices in OpenGL drawing. Polygons will be flat shaded unless normals are applied to them. A normal is a vector that is perpendicular to the polygon and points in the direction the polygon is facing. Remember polygons with vertices defined in a counter-clockwise winding points forward per the "right-hand rule". Polygon shading is based on the angle between the normals and the light source. Normals are applied to each vertex in the same way colors are, but is usually just defined at the start of each polygon definition. When a polygon's normals point directly at the light source, they are brightly shaded; and are darker shaded when the angles are skewed. You can refer to standard OpenGL documentation for more information if needed.
Example
fglNormal(1,0,0);
fglPopMatrix ()
Pops the current OpenGL drawing context from the matrix stack
Description
Pops the current OpenGL drawing context from the matrix stack, or in other words returns to the space on the top of the stack. The OpenGL stack stores the space matrix in a LIFO fashion. You can refer to standard OpenGL documentation for more information if needed.
Example
fglPopMatrix();
fglPushMatrix ()
Pushes the current OpenGL drawing context onto the matrix stack
Description
Pushes the current OpenGL drawing context onto the matrix stack which can later be retrieved with glPopMatrix(). If you are drawing more than one object and you don't want the glTranslated, glRotated or glScaled to affect the next objects, you should use glPushMatrix and glPopMatrix. The OpenGL stack stores the space matrices in a LIFO fashion. You can refer to standard OpenGL documentation for more information if needed.
Example
fglPushMatrix();
fglRotate (num degrees, num x, num y, num z)
Rotates the current OpenGL drawing context by degrees around axis x,y,z
Description
Rotates the current OpenGL drawing context by degrees around an axis defined by the vertex (x,y,z). Anything drawn after a rotation is based on the new rotation of the axes. See glVertex3d for definition of the OpenGL xyz coordinate system. You can refer to standard OpenGL documentation for more information if needed.
Example
fglRotate(90,1,0,0);
fglScale (num x, num y, num z)
Scales the current OpenGL drawing context by x,y,z
Description
Scales the current OpenGL drawing context by the given scale parameters. See glVertex3d for definition of the OpenGL xyz coordinate system. Anything drawn after this command is based on the change in scale of the axes. You can refer to standard OpenGL documentation for more information if needed.
Example
fglScale(2,4,1);
fglTranslate (num x, num y, num z)
Translates the current OpenGL drawing context by x,y,z
Description
Translates the current OpenGL drawing context by the given translation parameters. See glVertex3d for definition of the OpenGL xyz coordinate system. Anything drawn after a translation is based on the new location of the axes. You can refer to standard OpenGL documentation for more information if needed.
Example
fglTranslate(15, 4, 0);
filebrowse (str extension, str description, str startpath)
Opens a file selection dialog
Description
Opens a file selection dialog that allows the user to select the specified file type(s). Different types should be separated by semicolons(;). The dialog's default directory is the path specified. The commands pdir() and cdir() can only be passed as the path parameter in C++.
Example
string filename = filebrowse("*.fsm; *.fsp; *.fsv; *.fss","FlexSim Files",pdir());
fileclose ()
Closes the FlexSim file interface
Description
Closes the FlexSim file interface and saves any data written to the file while it was open.
Example
fileclose()

Returns 1 if the file exists, 0 otherwise
Description
Returns 1 if the file exists, otherwise 0.
Example
if(fileexists("C:/myfile.txt"))
{
    fileopen("C:/myfile.txt");
    fpt("Hello World");
    fileclose();
}
fileisreadonly (str filename)
Description

Example
fileisreadonly(pdir() + "\\flexsim.exe")
fileopen (str filename [, str opentype])
Opens the FlexSim file interface
Description
Opens the FlexSim file interface. Returns 1 if successful. Returns 0 if an error is encountered.

Parameter 2 can be "w" for writing, "r" for reading, or "a" for appending. Default is "w". Use the commands fpt(), fpr(), fpf(), etc. to write to the opened text file. Use filereadline() to read a line from the file. Using this command, you can only have one file open at a time. To write to multiple files simultaneously, use the C standard fopen/fclose commands or C++ standard fstream classes in C++ or through a dll.

If in write mode, the contents of the file will be cleared, and the file pointer will be set to the top of the file. The file must be closed to save any data written to the file.
Example
fileopen("C:/myfile.txt", "w");
filereadline ()
Reads a line from the currently open file
Description
Reads a line from the currently open file. Used with fileopen()
Example
string nextline = filereadline();
fillarray (array thearray, num/treenode/string val1[, num/treenode/string val2, ...])
Deprecated, use the Array class
Description
This command is deprecated. Use the Array class to construct the array using an array literal: Array arr = [1, 2, 3];

 Fill a local array with values.
Example
fillwithatts (obj object, num attgroup)
Description
For developer use. Fill an object with attribute from an attribute group.
Example
fillwithatts(so(),1)
findmatch (num nr, num matchexpression[, returnexpression = count, num reverseorder = 0])
Description
Performs a matching test a defined number of times, and when a match is found, returns a user-definable value associated with that match. Within the match expression and return expression, "count" can be used to determine which iteration your are on in the check. This can be used to search in a list of things for a matching item or criterion. If returnexpression is not included in the call, then findmatch() will return the count associated with the matching expression. If no matches are found, findmatch() will return 0. If reverseorder is 1, then it will go backwards, assigning count to nr first, then nr - 1, etc. down to 1. If returnexpression is left out, then findmatch will return the count associated with the found match.
Example
int portNr = findmatch(current.outObjects.length, current.outObjects[count].subnodes.length < 5);
This example will return the output port number that corresponds to the first object it finds connected to current's output ports that has a content less than 5.

 treenode object = findmatch(current.outObjects.length, current.outObjects[count].subnodes.length < 5, current.outObjects[count]);
This example is similar to the previous example except it will return the object itself instead of the associated port number.

 int item2Rank = findmatch(current.subnodes.length, current.subnodes[count].type == 2);
This example will return the rank number of the first item found in current's queue that has an item type of 2.

findmax (num nr, num valueexpression[, returnexpression = maxvalue, num criterion = true, num reverseorder = 0])
Description
Iteratively evaluates an expression, and then returns the maximum value found, or a user-definable return value associated with that maximum value. Within the value expression, return expression and criterion, "count" can be used to determine which iteration you are on in the check. If the return expression is not defined, the maximum value found will be returned. Additionally, you can specify a criterion to filter out values as invalid. If criterion is defined and nothing meets the criterion, 0 will be returned.
Example
double latestCreation = findmax(current.subnodes.length, getcreationtime(current.subnodes[count]));
This example will return the maximum creation time of all items in current.

 int largestQueuePortNr = findmax(current.inObjects.length, current.inObjects[count].subnodes.length;
This example will return the input port number associated with the object with the largest queue of items.

 int largestQueuePortNr = findmax(current.inObjects.length, current.inObjects[count].subnodes.length, count, getitemstate(current.inObjects[count].first) == FR_STATE_READY);
This example is the same as the previous example, but additionally in includes a criterion that the first item in the upstream object must also have been released.

findmin (num nr, num valueexpression[, returnexpression = maxvalue, num criterion = true, num reverseorder = 0])
Description
Iteratively evaluates an expression, and then returns the minimum value found, or a user-definable return value associated with that minimum value. findmin() is the same as findmax() except it finds the minimum value instead of the maximum value. For more information, refer to the documentation for findmax().
Example
Refer to findmax()
findownerobject (node thenode)
Description
Like ownerobject(), this command returns the object node containing thenode. Unlike ownerobject(), this command does not cache the result, but searches in the tree for the "owner" node. For example when a TaskExecuter transfers from one NetworkNode to another on a network path, a coupling node is transferred to the new node to keep track of the TaskExecuter's current node, and findownerobject() is used to get access to the correct "owner" node.
Example
findownerobject(c)
findundorecordbyid (obj view, num id)

getdashboardcontrol (str id [, node startnode])
Returns a reference to the dashboard control associated with id
Description
Returns a reference to the dashboard control that has the ID value of id. This command will search through all open dashboards until it finds a control with matching ID. Passing in a value for startnode will cause the command to only search through the dashboard containing startnode. Dashboard controls include edit fields, buttons, comboboxes, etc.
Example
treenode accelEdit = getdashboardcontrol("accelEdit", c); //Searches through the current dashboard only
getdatastat (num stat, num/node nrSamples/parentNode, num sampler [, num p1, num p2, num p3])
Description
Calculates and returns a certain statistic of a data set.
stat - Can be one of the following values
STAT_MEAN - calculates the sample mean of the set
STAT_MIN - calculates the minimum value in a defined range of values. p1 is the first element in the range (default is the first element in the set), p2 is the last element in the range (default is the last element in the set), and p3 defines a stride, allowing you to look at every nth value (default 1). If either of p1, p2, or p3 is 0, then it will revert to that value's respective default.
STAT_MAX - calculates the maximum element in a defined range of values. p1, p2 and p3 are the same as for STAT_MIN
STAT_VARIANCE - calculates the unbiased variance of the data set
STAT_STD_DEV - calculates the unbiased standard deviation of the set
STAT_SUM - calculates the sum of the set
STAT_CONF_INTERVAL_HALF_WIDTH - calculates the confidence interval half-width of the set. Pass in p1 to define the desired confidence percentage. FlexSim will return precise values for percentages at 80%, 90%, 95%, 98%, 99%, and 99.8% and for sample sizes at or below 100 degrees of freedom. For percentages not in this set, FlexSim will "clamp" it to the nearest percentage ABOVE the percentage passed in. So if you pass in a 75%, it will return an 80% confidence interval. Since an 80% confidence interval will be a "wider" interval, we clamp up to be "safer" with the wider interval. Confidence intervals above 99.8 will simply return 0 (i.e. not valid). For degrees of freedom above above 100, it will assume 100 degrees of freedom.
nrSamples - defines the number of samples in the set.
Note: parameter 2 as a parentNode is deprecated and you should use the parameter 2 as nrSamples option because it encompasses the other and is more flexible. The following deprecated functionality: getdatastat(STAT_MEAN, myNode, 0, 0, 0, 0) can be represented using the newer option with: getdatastat(STAT_MEAN, myNode.subnodes.length, myNode.subnodes[count].value, 0, 0, 0)
sampler - an expression that gets the nth value in the sample.
Use count for determining which value is to be retrieved. Below are several examples:
For calculating the mean of all values in column 5 of global table GT1:
getdatastat(STAT_MEAN, Table("GT1").numRows, Table("GT1")[count][5])
For calculating the sum of all values in field "Time" of a bundle:
getdatastat(STAT_SUM, Table("MyBundle").numRows, Table("MyBundle")[count]["Time"])
Example

getfilebrowse (str extension, str extensiondescription[, str defaultreturn, str location, num savemode, node filelist])
Opens a standard windows file browser dialog window
Description
This command opens a standard Windows file browser dialog window. The files shown in the window will have the extensions defined in extension. Different extensions should be separated by semicolons (;) in extension. The text passed as description will be used in the file browser to describe the type of file to open. This command returns a string that is the path of the selected file. If no file is selected, or Cancel is pressed, the command returns an empty string. See filebrowse() command.
Example
string shapefile = getfilebrowse("*.3ds; *.wrl","3D shape files");

 This sets the variable shapefile to the path of a file chosen from a file browser that displays files with the .3ds and .wrl extensions.
getfilesindirectory (str directory, str extension, node destnode)
Description
Retrieves all files in the specified directory that match the specified extension, and populates the content of destnode with nodes holding the path to each matching file. The command returns the number of matching files that were found. The extension parameter should be the specific three (or sometimes four) letter extension that you want to get. For example, if you want all .fsm model files, specify the string "fsm". Also, if you pass "directories" as the extension parameter, then the command will retrieve the list of directories inside the directory. To get all files, no matter the extension, pass "*" as the extension parameter. File paths will be set on the string data (as opposed to the name) of nodes inserted into destnode.
Example

treenode destnode = Model.find("Tools").subnodes.assert("Files");
int nrfiles = getfilesindirectory(documentsdir(), "*", destnode);
for(int i = 1; i <= nrfiles; i++)
{
	mpt("file: ");
	mpt(destnode.subnodes[i].value);
	mpr();
}
getframe (obj object)
Gets the current Shape Frame being drawn for object
Description
Returns the current 3D shape frame that is being drawn for the object. If the 3D shape assigned to the object was named myshape.3ds, and if two additional 3D shapes with file names myshapeFRAME1.3ds and myshapeFRAME2.3ds resided in the same directory as myshape.3ds, then the two additional files would be loaded into FlexSim automatically at the same time myshape.3ds was loaded, and setting the object's frame from 0 to 1 to 2 would change the object's shape to each of the shapes defined by the three files in order.
Example
if(getframe(current) == 3)) setframe(current, 5);
getinput (obj involved)
Deprecated, use Object.stats.input.value
Description
This command is deprecated. Use Object.stats.input.value instead.

Example
double inval = getinput(current.centerObjects[1]);
getiteminvolved (obj item)
Gets the object reference stored in the FixedResource involved variable for the item
Description
This returns the object reference stored in the FixedResource involved variable for the item.
The FixedResource class allows sub-classes to store 1 involved variable on each flowitem. What these variables mean is dependent on the type of class.
For example, a Processor uses the involved variable to store a reference to the dispatcher called for a flowitem if the Processor is set to use operators for the process or setup time.
If you are using the explicit FixedResource class as an object in your model, you can use this command, along with the setitemvar, getitemvar, and setiteminvolved commands, to store variables on the items the object receives.
Example
getiteminvolved(current.first)
getitemsendto (obj item)
Gets the value of the evaluated sendto for the item
Description
This returns the value of the evaluated sendto for the item if it is in a FixedResource and has been released.
Example

FRSTATE_MOVEREQUESTED: The flowitem has been released, and a downstream object is ready to receive it, but the item is waiting to get picked up by a transport.
For more information, refer to the FixedResource documentation.
Example
getitemstate(so())
getitemtype (obj object)
Deprecated, use labels
Description
This command is deprecated. Use labels instead.

 Returns the itemtype value of a flow item.
Example
getitemtype(so())
getitemvar (obj item, num var)
Gets the value of a FixedResource variable for the item
Description
This returns the value of a FixedResource variable for the item. The var parameter should be either 1, 2, or 3. The FixedResource class allows sub-classes to keep up to 3 number variables on each flowitem. What these variables mean is dependent on the type of class.
For example, a Processor uses variable 1 to store the time the item started its processing time, and variable 2 to store the item's processing time.
If you are using the explicit FixedResource class as an object in your model, you can use this command, along with the setitemvar, getiteminvolved, and setiteminvolved commands, to store variables on the items the object receives.
Example
getitemvar(current.first, 3)

Example
double myval = getreportnum(current,3,0);
getrunstate ()
Returns 1 if the model is currently running, 0 if not
Description
Returns 1 if the model is currently running, 0 if not.
Example

gets (node thenode)
Deprecated, use treenode.value
Description
This command is deprecated. Use treenode.value instead.

 Gets the value of a node with string data.
Example
getsdtvalue (node sdtNode, str valName)
For developer use
Description
Primarily for developer use only. Returns the value of the named class member of a node that has "SimpleDataType" data. We discourage using this command in model code because you risk breaking forward-compatibility. Future versions may redefine class members and their names, so model code that accesses these values by name may not work in future versions.
Example
getshapeindex (str name)

Description
Get the index of a loaded shape by its file path name. The file path name used in this command must use double backslashes as shown in the example. Use View -> Media Files to see a complete list of currently loaded shapes with their associated file path names and indexes.
Example
getshapeindex("fs3d\\Operator\\BasicOperator\\Chest.3ds");

getstat (node object, str name, int flag [, var p1, var p2, var p3])
Returns the statistic value for the given object
Description
It is preferred to use Object.stats instead. Gets the specified statistic from the given object.
name - The name of the statistic. Valid names can be enumerated using function_s(object, "enumerateStatistics", targetNode). Documentation for the meaning of the various statistics that an object provides should be found in each object's documentation. The documentation may include spaces in the names of the statistics, for readability. In passing these as the name parameter to getstat(), you should remove all spaces.
flag - Can be one of the following values
STAT_CURRENT - returns the current value of this statistic
STAT_MIN - returns the minimum value of this statistic
STAT_MAX - returns the maximum value of this statistic
STAT_AVERAGE - returns the average value of this statistic
STAT_TIME_AT_VALUE - returns the total simulation time the stat spent at a given value (requires an additional p1/p2/p3 parameter designating the desired value). This is only valid if the stat is tracking its history or profile data, such as in objects' standard "State" statistics. See below for more information on this.

p1, p2, and p3 are for providing "requirements" to resolve the correct statistic. For example, a list has several per-partition statistics. In order to get a partition's statistic, you need to pass the desired partition ID as p1. Requirements depend on the statistic that is being retrieved.

 There are also several special stat names that you can use. They are: "State", "Output", "Input", "Content", "Staytime". If you use one of these names, the command will return the corresponding standard statistic of the object. Examples:
getstat(object, "Output", STAT_CURRENT) - returns the current (total) output of the object (same as object.stats.output)
getstat(object, "Content", STAT_AVERAGE) - returns the average content of the object
getstat(object, "State", STAT_CURRENT, 0) - returns the current state of the object (same as object.stats.state().value)
getstat(object, "State", STAT_TIME_AT_VALUE, 0, STATE_IDLE) - returns the total idle time of the object (0 designates the state profile, i.e. the default state profile)
getstat(object, "Staytime", STAT_MAX) - returns the maximum recorded stay time of the object
Note that some stats that do not make sense will not return valid data, such as average state, or average output.

STAT_TIME_AT_VALUE
If you want to get the STAT_TIME_AT_VALUE access, the statistic needs to track either historical or profile data. If it is an object's standard "State" statistic, FlexSim will automatically make it track its profile data, so you don't need to do any extra work for that. For other statistics, however, you will need to explicitly "subscribe" to the statistic to make it track its profile or history data. Historical data records each change of value and the corresponding simulation time of that value change. Profile data records the total time the variable was at each value. Only non-negative integer values are valid for profile data.

 To subscribe to a tracked variable, first find where the tracked variable statistic is in the tree. For example if it's the "Content" statistic, you'll likely find it at object>stats/stats_content. Then call the following command on the node: function_s(statNode, "addSubscriber", needsHistory, needsProfile, persist). The needsHistory and needsProfile parameters are booleans telling which data you want to track. The persist is a boolean that tells if you want it to track these statistics indefinitely going forward. The tracked variable tries not to continue tracking extra data if it is not needed. If nobody subscribes to its data "persistently", then it will discontinue recording the data if it doesn't get subscribers for a while (I think after 5 or so model resets with no subscribers).

 Recording historical data will allow you to get the STAT_TIME_AT_VALUE access. However, using historical data for getting STAT_TIME_AT_VALUE is slower than if you track profile data. With historical data, it must traverse the entire history to calculate STAT_TIME_AT_VALUE, whereas if you track profile data, it stores the total time at the value directly in the profile data.
Example
getstatenum (obj object [, num stateprofilenr])
Deprecated, use Object.stats.state().value

 Returns the state of an object in numeric form.
Example
getstatenum(current);
getstaterecord (num record)
Deprecated
Description
This command is deprecated. Returns a state change record that has been recorded for the Full History Report. A state change record is created every time an object changes state if Full History is enabled. The parameter passed to this function is the number of the record (beginning at 1) that the user wishes to retrieve. If this command is called in C++, the return value is a StateRecord*. If this command is called in FlexScript, the return value can be assigned to an int.
Example
See the example for getnumstaterecords().
getstaterecordvalue (num record, num value)
Deprecated
Description
This command is deprecated. Returns one of the values from the state change record that is passed in as the first parameter to the function. This record is the return value from a call to getstaterecord(). The value passed to this function as the second parameter indicates which value from the state change record the user wishes to retrieve:
0 = The record ID. This is the record\'s row number in the movement table.
1 = The time of the state change.
2 = The state that the object changed to.
3 = The object that changed state. This is returned as an int and should be converted to a treenode using tonode().
Example
See the example for getnumstaterecords().
getstatestr (obj object)
Deprecated, use Object.stats.state().valueString
Description
This command is deprecated. Use Object.stats.state().valueString instead.

 Returns the state of an object as a text string.
Example
getstatestr(current);
getstream (node object)
Returns a unique random stream associated with the object
Description
Returns a unique random stream associated with the object.

Returns the number stored in the object's stream attribute. If the object does not yet own a stream attribute, or if its stream attribute is 0, FlexSim will assert the attribute and assign it a unique stream number. If the object passed into the function does not have object data, it will store the unique stream in a subnode. This subnode will be destroyed on model reset and reassigned during the model run as needed.

 Assigned streams start at stream 101 and increase as they are assigned.
Example
uniform(0, 1, getstream(current))
getsystemmetric (num metric[, HWND win])

Description
This command is deprecated. Use the TaskSequence and TaskSequence.Task classes instead. Returns a reference to either the first or second involved object for the nth ranked task of the specified task sequence.
The ranking is based on the initial ranking of the task, when the task sequence was initially created and tasks were
added. It is not based on the ranking at a given time in the simulation, as tasks may have already been completed
and subsequently destroyed. The third parameter defines which involved object it is (1 or 2)


You can also pass a reference to the TaskExecuter as the first parameter, and the value 0 as the second parameter

and tasks were added. It is not based on the ranking at a given time in the simulation, as tasks
may have already been completed and subsequently destroyed.

You can also pass a reference to the TaskExecuter as the first parameter, and the value 0 as the second parameter
to get the task type of the object's currently active task.

Gets information regarding the current state of a taskexecuter on a node network
Description
Returns information regarding the current state of a taskexecuter on a node network. Valid queries are as follows:

NETWORK_INFO_DEST_NET_NODE_RANK - returns the destination column/rank of the network node that the TE would travel to were he to be given a travel task to destobj. Usually this will simply be the network node attached to destobj, but if multiple network nodes are attached to destobj, the command will find the closest one.
NETWORK_INFO_ORIGIN_NET_NODE_RANK - returns the origin column/rank of the network node that the TE would start from were he to be given a travel task to destobj. Usually this will simply be the current network node where the TE is located, but if that network node has virtual exits, the command will find the virtual exit that renders the shortest travel distance.
NETWORK_INFO_DISTANCE - returns the shortest travel distance to the destination object through the network.
NETWORK_INFO_CUR_DIST_ALONG_EDGE - Only valid when the TE is actively doing a travel task. This returns the current distance that the TE has traveled along its current network edge. For this query, destobj should be NULL.
NETWORK_INFO_CUR_TRAVEL_ORIGIN_RANK - Only valid when the TE is actively doing a travel task. This returns the rank of the origin node at which the TE starts its current travel operation. For this query, destobj should be NULL.
NETWORK_INFO_CUR_TRAVEL_DEST_RANK - Only valid when the TE is actively doing a travel task. This returns the rank of the destination node to which the TE is traveling for its current travel operation. For this query, destobj should be NULL.

For zones, it is the set of tokens that have entered the zone. For a list, it is the set of tokens who have been pushed to the list. Returns an Array containing the result.

instanceObject - The object associated with the desired process flow instance. For general process flow's this is the same as the process flow itself. For task executer and fixed resource process flows, it is the 3D object, i.e. task executer or fixed resource, associated with the process flow instance. If executed from within process flow activity logic, this will usually just be "current". If you pass NULL here, it will get tokens for all instances.

activityOrAsset - The target activity or shared asset. If NULL, the command will return all active tokens in the entire process flow instance.

flags - Defines optional flags. If GET_TOKENS_REQUESTS is passed for a shared asset, it will return the set of tokens requesting the shared asset (i.e. tokens waiting to enter a zone, tokens back ordering on a list, etc.).

mean = γ + β(π⁄α)csc(π⁄α) for α > 1
variance = β²(π⁄α){2csc(2π⁄α) − (π⁄α)[csc(π⁄α)]²} for α > 2

Possible Applications:
Used to model the time to perform some task.
Example
loglogistic(0, 1, 2, 5);

A loglogistic distribution with a location (shift) of 0, a scale of 1, a shape factor of 2 and random stream number 5.
lognormal (num location, num normalmean, num normalstdev[, num stream])
Returns a random sample from a lognormal distribution
Description
lognormal() and lognormal2() are similar functions, but with different parameter definitions. lognormal() uses parameter definitions as defined on wikipedia and other sites. lognormal2() uses parameters as defined in the latest versions of Expertfit. Essentially, the parameters can be converted as follows:

 lognormal( location, normalmean, normalstdev ) = lognormal2( location, Math.exp( normalmean ), normalstdev )
lognormal2( location, scale, shape ) = lognormal( location, Math.log( scale ), shape ) (Math.exp(x) is e raised to the x power, and Math.log(x) is the natural logarithm of x.)

 Please make sure you use the right distribution. Using the wrong distribution could result in bad simulation results.

 lognormal( location, normalmean, normalstdev, stream ) is a continuous probability distribution.

Inputs:
location : ( - ∞, ∞ )
normalmean such that ( Math.exp( normalmean ) > 0 )
normalstdev such that ( normalstdev > 0 )
stream is a reference to one of FlexSim's random number streams {0,1,2,...}

Outputs:
range = ( location , ∞ )
mean = location + Math.exp( normalmean + normalstdev²⁄ 2)
variance = Math.exp( 2*normalmean + normalstdev² ) [ Math.exp( normalstdev² ) − 1 ]

Probability Density Functions:



Possible Applications:
Used to model the time to perform some task, and to model quantities that are the product of a large number of other quantities. It can also be used as a rough model in the absence of data.

Comments:
The probability density for the lognormal distribution takes on shapes similar to gamma( normalstdev, normalmean ) and weibull( normalstdev, normalmean ) densities for normalstdev > 1, but can have a large spike close to x=0 that is often useful.
Example
lognormal2 (num location, num scale, num shape[, num stream])
Returns a random sample from a lognormal distribution
Description
lognormal() and lognormal2() are similar functions, but with different parameter definitions. lognormal() uses parameter definitions as defined on wikipedia and other sites. lognormal2() uses parameters as defined in the latest versions of Expertfit. Essentially, the parameters can be converted as follows:

 lognormal( location, normalmean, normalstdev ) = lognormal2( location, Math.exp( normalmean ), normalstdev )
lognormal2( location, scale, shape ) = lognormal( location, Math.log( scale ), shape ) (Math.exp(x) is e raised to the x power, and Math.log(x) is the natural logarithm of x.)

 Please make sure you use the right distribution. Using the wrong distribution could result in bad simulation results.

Example
double cycletime = lognormal2(0, 29.8, 0.31, 5);

Set the cycletime variable to a lognormal2 distribution with location parameter 0, scale parameter 29.8, shape parameter 0.31, and random stream number 5.
lognormalmeanstdev (num mean, num stdev[, num stream])
Returns a random sample from a lognormal distribution
Description
This command is an alternative to the lognormal2 command, used in the absence of data. You can specify the mean and standard deviation, and the command will calculate from those parameters the proper location, scale, and shape parameters for the lognormal2 command, and return a sample from that distribution. Note that the shape of the distribution is pre-defined to be a bell-shaped curve with a reasonably long right tail. Hence this command isn't as flexible as the lognormal2 command. This command, similar to the triangular distribution, should be used in the absence of data, where you know the mean and standard deviation of the distribution, and you assume that the distribution is right-skewed (it has a longer right tail), but you do not have a real data set to fit to a distribution. Refer to lognormal2 for more information. Relating to the diagram describing the lognormal2 distribution, the lognormalmeanstdev command uses a normalstdev/shape value of 0.75 to define its shape. Note that since the shape of the distribution is hard-set, depending on the mean and standard deviation values, this may return a negative value.
Example
double cycletime = lognormalmeanstdev(10, 2);
This example will return a random value that follows a right-skewed lognormal distribution with a mean of 10 and standard deviation of 2.

Description
For developer use. This command executes a function that is defined on thenode. Thenode must be toggled as either a C++ node or a Flexscript node. If the node is C++, the model must be compiled before calling this command. Any parameters that need to be passed to the function are passed as par1, par2, etc. Up to 10 parameters may be passed. The values that are passed using this command must all be numbers, but can then be accessed and recast from within the function called using the command param(x) where x is the number of the parameter.

nodefunctionlisten (node theNode, node relayNode[, num flags, par1, par2, ... par10])
Description
For developer use. This command will create a listening mechanism where whenever nodefunction() is called on theNode, relayNode will also be executed. flags is a bitwise mask of one of the following values:
NFL_PRE_LISTEN: The listening function will be called before theNode is called.
NFL_LISTEN: (default) The listening function will be called after theNode is called.
NFL_PERSIST: The listener will persist across model resets.
NFL_PASS_THROUGH_PARAMS: When theNode is called, the parameters passed into that function will also be "passed through" into the listening node. In this case, par1, par2, etc. are not used.
When the listening node is called, if it returns NFL_STOP_LISTENING, the listener mechanism will be removed and the listening node will no longer be called. The return value is a reference to a node associated with the listening. If this node is later deleted, the listening mechanism will stop.
Example
nodefunctionlisten(getvarnode(current, "entrytrigger"), current.entrylistener);
nodeinsertafter (node targetnode)

σ is the scale parameter ( 0, ∞ )
stream is a reference to one of FlexSim's random number streams {0,1,2,...}

Outputs:
range = ( - ∞, ∞ )
mean = μ
variance = σ²

Probability Density Functions:



Possible Applications:
Used to model various types of error such as machined hole diameters for large quantities of parts. This distribution is not used much in simulation because variance found in real processes do not typically follow a symmetric distribution such as this.

Comments:
The normal distribution is completely symmetric meaning values below the mean have the same probability for occurance as values above the mean. The mode and mean are equal for the normal distribution. When using this distribution, be aware that negative values can be returned, and therefore truncating the distribution at 0 may be necessary as shown in the example below.
Example
double thickness = Math.max(0.001, normal(5, 1.2));

The thickness is set a normal distribution having a mean of 5 and a standard deviation of 1.2 that is truncated for values less than 0.001. No random stream has been declared, so the default stream number 0 will be used to generate variates from the distribution.

 Connect two objects, adding needed ports. Object1 will have an output port added, and object2 will have an inport added as needed. Then the ports are connected.
Example
connect(so(),so().next)
objectexists (obj object)
Check if an object exists
Description
If you're trying to test if an object exists when using dot syntax you can omit the objectexists. For example, if (current.labels["MyLabel"]) or if (current.next).

 This command returns true (1) if the object specified as object exists in the tree. If the object does not exist, this command returns false (0).
Example
if (objectexists(next(current)))
{
moveobject(item, next(current), 1);
}

 This checks to see if there is an object in the tree after current. If there is, the object referenced by item is moved into it through port number 1.
objectshapecode (obj object)
Deprecated, use getshapeindex()
Description
This command is deprecated. Use getshapeindex() instead.

 Get the index of the object's default shape. The media list of FlexSim will keep a list of all loaded shapes. Each shape has a corresponding name and an index. This command will return the index corresponding to the objects default shape.
Example
objectshapecode(so())
objectsoundcode (obj object)
Gets the index of object's default sound
Description
Get the index of the object's default sound. The media list of FlexSim will keep a list of all loaded sounds. Each sound has a corresponding name and an index. This function will return the index corresponding to the objects default sound assuming the object has a sound and soundindex attribute (default objects do not at this time)
Example

opavailable (obj object, num outputportnum)
Description
Returns a 1 if the downstream object through the specified object's output port is available. Particularly, it checks if the downstream object exists, if it is stopped, if its input is open, and if the connected input port is open. This function returns 0 if the downstream object isn't available.
Example
opavailable(current,1)
openallip (obj object)
Open all input ports of object
Description
Open all input ports of object. If an input port has a pass-through state as a result (both connected ports are open), both objects will be sent a notification message that the port has become "ready". The object with the input port will receive an OnInOpen message and the object with an output port will receive an OnOutOpen message. During traversal of the ports, any given port will only allow pass-through evaluation once. Modelers should only use this command when working with fluid objects because the internal behavior of discrete objects controls the opening and closing of their ports, and therefore this command may be overridden. For discrete objects the modeler is referred to openinput() and resumeinput().
Example
openallip(current)
openallop (obj object)
Open all output ports of object
Description
Open all output ports of object. If an output port has a pass-through state as a result (both connected ports are open), both objects will be sent a notification message that the port has become "ready". The object with the input port will receive an OnInOpen message and the object with an output port will receive an OnOutOpen message. During traversal of the ports, any given port will only allow pass-through evaluation once. Modelers should only use this command when working with fluid objects because the internal behavior of discrete objects controls the opening and closing of their ports, and therefore this command may be overridden. For discrete objects the modeler is referred to openoutput() and resumeoutput().
Example
openallop(current)
openflexsimchart ([str filename1] [,str filename2])
Deprecated
Description
This command is deprecated.
Example
openglcolor (num red {0-1}, num green {0-1}, num blue {0-1}, num opacity {0-1})

Description
This command is deprecated. Use fglColor() instead.
Example
opengllighting (num on/off)
Deprecated, use fglEnable(GL_LIGHTING) and fglDisable(GL_LIGHTING)
Description
This command is deprecated. Use fglEnable(GL_LIGHTING) and fglDisable(GL_LIGHTING) instead.
Example
openinput (obj object)
Deprecated, use Object.input.open()
Description
This command is deprecated. Use Object.input.open() instead.

 This command unblocks the input of the object after it has been previously blocked with the closeinput() command. It is necessary that both the input ports themselves, and the input in general, are open before entry will be allowed. It is advised that modelers never use this command in any field other than the OnMessage field which has been triggered with the senddelayedmessage() command, because commands which open ports often spawn several other activities that shouldn't be performed during transitional events. Compare this command with resumeinput().
Example
if (current.subnodes.length < maxcontent)
openinput(current);
openip (obj object, num inputportnum)
Open one input port of object
Description
Open just inputportnum of object. Opening an input port of an object will allow entry to the object through that port. Modelers should only use this command when working with fluid objects because the internal behavior of discrete objects controls the opening and closing of their ports, and therefore this command may be overridden. For discrete objects the modeler is referred to openinput() and resumeinput().
Example
openip(so(),1)
opennodeedge (obj networknode, num edgenum)
Opens entry to the networknode's edge
Description
Opens entry to the networknode's specified edge number. Closing a node's edge with closenodeedge() blocks travelers from entry onto the edge. This command opens the edge up again.
Example
opennodeedge(current.centerObjects[1], 3);

Opens node edge 3 of a NetworkNode connected to center port 1 of the current object.
openop (obj object, num outputportnum)
Open one output port of object
Description
Open just outputportnum of object. Opening an output port of an object will allow exiting from the object through that port. Modelers should only use this command when working with fluid objects because the internal behavior of discrete objects controls the opening and closing of their ports, and therefore this command may be overridden. For discrete objects the modeler is referred to openoutput() and resumeoutput().
Example
openop(so(),1)
openoutput (obj object)
Deprecated, use Object.output.open()
Description
This command is deprecated. Use Object.output.open() instead.

 This command unblocks the output of the object after it has been previously blocked with the closeoutput() command. It is necessary that both the output ports themselves, and the output in general, are open before exiting is allowed. It is advised that modelers never use this command in any field other than the OnMessage field which has been triggered with the senddelayedmessage() command, because commands which open ports often spawn several other activities that shouldn't be performed during transitional events. Compare this command with resumeoutput().
Example
if (current.subnodes.length > mincontent)
openoutput(current);
opipno (obj object, num outputportnum)
Input port number that is connect to outputportnum of object
Description
This command returns the input port number that is connected to outputportnum of object.
Example
int otherport = opipno(current,1);

 This sets otherport to the number of the input port that current's first output port is connected to.
opopen (obj object, num outputportnum)
Description
Returns a 1 if the outputportnum on object is open. Otherwise returns zero.
Example
opopen(current,1)
opready (obj object, num outputportnum)
Description
Returns a 1 if the outputportnum of object is open and the connecting input port of the other object is also open. Otherwise a 0 is returned. This command does not take into consideration whether or not the output of this object or the input of the connecting object are currently open.
Example
opready(current,1)
optimizenetwork ()
Causes the model's network navigator to regenerate its distance table
Description
Causes the model's network navigator to regenerate its distance table.
Use this command if you are dynamically connecting edges in your network during the simulation run.

Example
optquest(...)
or (num/node condition1, num/node condition2)
Deprecated, use the || operator
Description

Example
outobject (obj object, num outputportnum)
Deprecated, use Object.outObjects[]
Description
This command is deprecated. Use Object.outObjects[] instead.

 Reference the downstream object connected to an upstream object's output port.
Example
outputopen (obj object)
Returns 1 if the object's output is open, 0 otherwise
Description
Returns 1 if the object's output is open, 0 otherwise. The closeoutput(), stopoutput(), openoutput(), and resumeoutput() commands affect the return value of this command. The commands like closeop() and closeallop() do NOT affect the return value.
Example
if(outputopen(current)) current.output.close;

If the output is open for the current object, then close the output.
outputtreecontent (node containernode, str path+filename)
Writes the data of all nodes in the tree under containernode to a text file
Description
Writes the data of all nodes in the tree under containernode to a text file on disk. If file does not exist, it will be created. For more functionality, use menu option: Stats | Model Documentation.
Example
outputtreecontent(model(),"C:/MyModelDocumentation.txt")
ownerobject (node thenode)
Gets the object that "owns" the executing node, usually the current object
Description
This command returns the node with object data attached to it that is the start of the sub-tree that thenode is in. In other words, it returns the object node that contains thenode. The result of this command is cached on thenode, so that subsequent calls to ownerobject(thenode) do not search in the tree, but return the cached result. If thenode subsequently changes parent, ownerobject(thenode) will return the cached result.

This command is used in most code fields and trigger fields to set the access variable current. In these fields, c references the node that contains the code, and ownerobject(c) references the object that "owns" that node.

Example
string objname = ownerobject(c).name;

 This sets objname to the name of the object that contains the node referenced by c. The c usually refers to the node where the code is being written.

treenode current = ownerobject(c);

This example is present in most code fields in FlexSim, and retrieves access to the "current" object.

If the pull evaluation is true, this command pulls the item immediately. This command returns 1 if the item was successfully pulled and 0 if not. If the item cannot be pulled for any of various reasons (such as closed ports or the item not being released), then this command returns 0. The bypassflags parameter is a bitwise combination of macros that start with BYPASS_ to specify certain criteria to ignore in determining item availability. You can specify BYPASS_ALL to immediately pull the item regardless of availability.
Example

Example
rackdrawfilledcell (obj rack, num bay, num level, num x, num y, num z, num sx, num sy, num sz, num red, num green, num blue)
Draws a box in the rack's given bay and level
Description
Draws a box in the rack's given bay and level. x,y, and z are numbers between 0 and 1 representing the percentage into the cell to start drawing the box. sx, sy, and sz are numbers between 0 and 1 representing the size percentage of the box. Red, green and blue specify the color of the box.

To ensure that the boxes are drawn correctly, you should disabled OpenGL textures with fglDisable(GL_TEXTURE_2D) before calling this command in a draw trigger.
Example
fglDisable(GL_TEXTURE_2D);
for (int bay = 1; bay <= 5; bay++) {
    for (int level = 1; level <= 3; level++) {
        rackdrawfilledcell(current, bay, level, 0,0,0, 0.5,1,1, 255,0,0);
    }
}
fglEnable(GL_TEXTURE_2D);

This example draws red boxes in bays 1-5, levels 1-3, that fill half of each cell's volume (sx = 0.5, sy =1, sz = 1).
rackdrawvirtualcontent (obj rack, num bayfillperc, num levelfillperc, num itemdepth, num red, num green, num blue, num virtualonly)
Draw the rack's virtual content
Description
Draws the rack's "virtual" content. This command will usually only be used if you are recycling flowitems using the rackrecycleitem command. When this command is executed, the rack goes through its content table, and draws a box for every flowitem in the rack, at its appropriate bay and level. If virtualonly is 1, then it will only draw a box in spots where a slot is filled, but no flowitem is present (the flowitem has been recycled). Bayfillperc and levelfillperc are values between 0 and 1, and specify the percent of the cell to fill with the drawn box. Item depth is the size each item takes up in the rack. For a floor storage rack, this the z size of the items. For a regular rack, it is the y size of the items.
Example
rackdrawvirtualcontent(current, 0.9,0.9,3, 256,0, 0, 1);

rackgetcellvar (obj rack, num bay, num level, num varnum, node storagenode)
Description
Returns the value stored in a three dimensional table with rows representing the rack's bays,
columns representing the rack's levels,
and sub-nodes of table cells representing different stored values for each cell of the Rack.
This allows you to store custom information for each cell of the rack.
Bay, level, and varnum reference bay (row), level (column), and variable number (sub-node rank) in the table.
storagenode references the node you have stored this table on. Usually this should be a label on the Rack.
Example

Sets theitem pointer to the second flowitem in bay 5, level 4 of the current object.
rackgetitemcellrank (obj rack, obj item)
Gets the item's rank within the rack's cell
Description
Returns the rank of the item within its given cell in a rack.
Example
int theRank = rackgetitemcellrank(current, item);
rackgetlevelloc (obj rack, num bay, num level)
Gets the y or z location of the level relative to the rack's origin
Description
Returns the y or z location of the given level of the rack, relative to the rack's origin.
If the rack is a floor storage rack, this returns the y rz.
If the rack is a normal rack, this returns the z rz.
Example
rackgetlevelloc(current, 5, 4);

Returns the y or z location of bay 5, level 4.
rackgetlevelofitem (obj rack, obj item)
Gets the level number of the rack that the item is placed in
Description

Set the levelnum variable to the level number containing item in the current rack.
rackgetlevelsize (obj rack, num bay, num level)
Gets the y or z size of the level of the rack
Description
Returns the y or z size of the given level of the rack.
If the rack is a floor storage rack, this returns the y size.
If the rack is a normal rack, this returns the z size.
Example
rackgetlevelsize(current, 5, 4);

Returns the y or z size of bay 5, level 4.
rackgetnrofbays (obj rack)
Gets the number of bays rack has
Description
Returns the number of bays that the rack has.
Example
return duniform(1,rackgetnrofbays(rack));

This returns a random number between one and the number of bays on the rack. This is the same as the "Random" option of the place in bay pick list.
rackgetnroflevels ( obj rack [,num bay ] )
Gets the number of levels in the bay of the rack
Description
Returns the number of levels in the specified bay of the rack. If no bay parameter is passed into the function, then the nroflevels in the first bay will be returned.
Example
return duniform(1,rackgetnroflevels(rack, baynum));

This returns a random number between one and the number of levels on the chosen bay of the rack. This is the same as the "Random" option of the place in level pick list.
rackrecycleitem (obj rack, obj item, num binrank)
Recycles the flowitem into the flowitem bin
Description
Recycles the flowitem into the flowitem bin specified.
This command is for advanced users, and should not be used unless you are prepared to do some debugging.
Bin rank should be the rank of the flowitem in the flowitem bin (textured colored box = 5, etc.).
When this command is called, the flowitem is recycled, but the spot where it is located is designated as taken,
and further flowitems will be put into the rack as if this spot is already filled.
This can significantly increase the speed of a model.
Subsequent commands to rackgetbaycontent(), rackgetcellcontent(), etc. will return values as if the item were still there.
However, rackgetitembybaylevel() will return NULL for an item that has been recycled and has yet to be restored.
Make sure the item is not released or waiting for a transport before calling this command.
Note that max content of the rack will not work properly if this command is used. Also you will need to eventually restore the item using the
rackrestoreitem() command.
Example
rackrecycleitem(current, item, 5);

This recycles the flowitem into the 5th ranked flowitem of the flowitem bin (usually the textured colored box).
rackrestoreitem (obj rack, num binrank, num bay, num level, num position)
Restores a flowitem from the flowitem bin into the bay and level
Description
Restores a flowitem from the flowitem bin into the given bay and level.
Example
rackrestoreitem(current, 5, 7, 3, 1);

This restores a flowitem from the 5th ranked flowitem of the flowitem bin (usually the textured colored box) into bay 7, level 3, position 1 of the rack.
racksetcellcontent (obj rack, num bay, num level, num contentval)
Sets the virtual content of the rack's cell to contentval
Description
Sets the "virtual" content of the rack's cell to the specified value.
This should only be used if you are recycling and restoring items to the rack with rackrecycleitem() and rackrestoreitem().
You will usually use this command to set an initial "virtual" content on reset.
Example
racksetcellcontent(current, 5, 3, 2);
racksetcellvar (obj rack,num bay, num level, num varnum, num setvalue, node storagenode)
Description
Sets the value in a three dimensional table with rows representing the rack's bays,
columns representing the rack's levels,
and sub-nodes of table cells representing different stored values for each cell of the Rack.
This allows you to store custom information for each cell of the rack.
Bay, level, and varnum reference bay (row), level (column), and variable number (sub-node rank) in the table.
Setvalue is the value to set it to.
storagenode references the node you have stored this table on. Usually this should be a label on the Rack.
Example
racksetcellvar(current, 5, 3, 2, 4.6, current.labels["storageData"]);

This sets the 2nd value of bay 5, level 3 to 4.6
radianstodegrees (num value)
Deprecated, use Math.degrees()
Description
This command is deprecated. Use Math.degrees() instead.

 Convert radians to degrees
Example
randantithetic (num on/off)
Description
Makes number streams antithetic. Using this command, users can switch random streams to generate numbers between 1 and 0; rather than the default of 0 to 1. This is helpful for determining if random numbers are having a big affect on the results of the model. It's also useful when experimenting with massive models and there isn't sufficient time to run the model for multiple iterations as required for good statistical sampling. The user can then choose to do just one regular run and one antithetic run of the model to obtain two diametrically apposed results. These two results can be averaged for an approximation that is somewhat better than if each run of the model used random stream generators without antithetic sampling.
Example
randantithetic(1);
randinit (num stream, num seedvalue[, num seedvalue2, num seedvalue3, num seedvalue4, num seedvalue5, num seedvalue 6])
Initializes a random stream
Description
Initializes the random number stream by setting its first value to seedvalue. Although there are an unlimited number of random number streams available to the user, only the first one hundred streams numbered 0 through 99 have been initialized when the FlexSim application is opened. To create a new stream, simply execute the randinit() command for the new stream. For instance, executing randinit(105, 7628912) will create a new stream number 105 if it does not currently exist, and set its initial seed value to 7628912.

 If "Repeat Random Streams" has been selected in the Statistics menu, then streams 0 through 99 will be automatically initialized with a default seed value for that stream whenever the model is reset. For streams 100 and above, you must use the randinit() command to set their initial seed values if you wish to repeat their random streams. Any positive integer may be passed in as the seedvalue for a random number stream. If you pass in a seedvalue of 0 for random streams 0 through 99, it is a special case that will initialize them to their default seed values.

seedvalues 2 through 6 are only used if you are using FlexSim's Combined MRG random number generator. To enable this generator, call maintenance(49,1) when your model opens.
Example
Example 1:

 randinit(5, 73241);

 Initialize FlexSim's random stream number 5 with a sead value of 73241.

 Example 2:

 randinit(2,0);
for(int i = 100; i <= 199; i++)
{
    randinit(i, realtime(1) * uniform(0, 1, 2));
}

 First initialize standard stream number 2 to its default seed value, then execute a loop for 100 iterations to create (if necessary) streams 100 through 199 and set their initial seed value to the product of a random number pulled from stream 2 and the current number of real clock seconds.
randnext (num stream)
Description
For development use. Returns the next random number from the stream. This command is used to pull random samples from probability distribution functions.
Example
randnext(1);

Gets the next random number in the stream of random numbers associated with stream generator number 1.
randomwalk (num location, num scale, num shape[, num stream])
Description
Generates a continuous random variate from a random walk distribution with parameters as defined.
Example
randstate (num stream[, seednr])
Gets the current state value for the random number stream
Description
Returns the current state value for the specified random number stream. This state value may be useful as the seed value in the randinit() command for the purposes of restarting a saved state model from the same point in the random number stream of the initial run.

 seednr is only needed if you are using FlexSim's Combined MRG random number generator, in which case the seednr should be a value 1-6 defining which seed value you want to get the state on. Refer to randinit() for using the Combined MRG.
Example
int curstate = randstate(5);

Set the curstate variable to the current random integer value stream number 5.
rank (obj parent, num index)
Deprecated, use treenode.subnodes[]
Description
This command is deprecated. Use treenode.subnodes[] instead.

 Reference a child node by rank.
Example
rankfromnetnode (obj netnode)
Returns the member rank of network node netnode
Description
Takes a network node reference and returns the member rank of that network node. Each network node has a specific "member rank", which is used as a row/column reference in the network's distance and next node tables. The first network node that is added to a model gets member rank 1, the second gets member rank 2, and so on.
Example
int memberrank = rankfromnetnode(current);
rankobj (obj container, num rank)
Deprecated, use Object.attrs[]
Description
This command is deprecated. Use the treenode.attrs's [] operator instead.

 Gets a reference to the ranked node in the object's attribute sub-tree at rank.
Example
reacquirepreemptedresource (node token, node instance, node preemptedObject, node info, node activeProcess, int sameAsLast)
Description
Example
reacquirepreemptedresource(token, current, preemptedObject, info, activeProcess);
realtime (num timecode)
Gets the real clock time
Description
Returns the real clock time in a variety of formats based on the timecode:

1 = the number of seconds since midnight, Jan 1, 1970
2 = the number of milliseconds since the last second change
10 = a time string with format hh:mm:ss
11 = a date string with format mm/dd/yy
12 = a date/time string with format Mon Nov 15 15:49:12 2004
Example
string curdatetime = realtime(12);
reassignnetnode (obj taskexecuter, obj networknode)
Description
TaskExecuters using a NetworkNode system are always associated with a specific NetworkNode in the system (red line graphic) which continually changes as they travel around. This command reassigns the specified taskexecuter to networknode.
Warning!!! Do not execute this command unless the TaskExecuter is on a network, and unless you know the TaskExecuter is not currently executing a travel task.
Example
reassignnetnode(current, current.centrObjects[5]);

Reassign the current TaskExecuter to the NetworkNode connected to its fifth center port.
reassignticker (obj fluidobject, obj ticker[, int resortticker])
Reassigns the Fluid Object's ticker
Description
Changes the Fluid Object passed in as the first parameter from the control of its current Ticker, to the Ticker that is passed in as the second parameter. The object will then have its fluid movement calculated whenever the new Ticker's tick-time elapses. It is recommended that Fluid Objects that are connected to each other always be controlled by the same Ticker. If resortticker is 1, then the new Ticker will immediately resort its list of controlled objects. This may change the order that some fluid objects are evaluated and may have side-effects in the model behavior.
Example
reassignticker(current,Model.find("Ticker2",1);
rebindobjectattributes (node thenode)
Rebinds object attributes
Description
Rebinds object attributes for the given node. If you delete or add an attribute to an object, the object's attribute cache will not immediately reflect that change, so you can call rebindobjectattributes to update the object's attribute cache. This is the same as right-clicking on the object and selecting Edit|Rebind Object Attributes.
Example
rebindobjectattributes(c)
receiveitem (obj station [, num port ] )
Tells the FixedResource to open inputs and receive a flowitem
Description
Tells the FixedResource station to open its inputs and receive a flowitem.
The port parameter is optional, and should only be used if you know exactly which port you want to receive from. If the port parameter is specified, this object will try to receive any item from the upstream object if its corresponding output port is open, ignoring any items' previous send-to return values (similarly to how pull logic works). This function should be executed only once to receive an item, and it should only executed again once you have received (or have confirmed reception of) that item.
See also releaseitem() command. This function should only be used from within a BasicFR's or BasicConveyor's code fields, as other objects implement receiveitem() on their own.
Example
receiveitem(current)
recover (num phase)
Load recovery files
Description
Load recovery files. phase: 1 or 2
Example
recover(1)
recycleitem (obj item , num binrank )
Recycles the flowitem to the flowitem bin
Description
Recycles the specified flowitem to the flowitem bin. Binrank should be the rank in the flowitem bin to recycle to (texturedcoloredbox = 5, etc.)
Example
recycleitem(item, 5);
redirectconsole (num console:output/system/compiler/trace, obj view)
Redirects any prints to a given console
Description
This redirects any prints to a given console so that they will instead be printed to the view text of the specified view. CONSOLE_OUTPUT redirects the output console, CONSOLE_SYSTEM redirects the system console, CONSOLE_COMPILER redirects the compiler console, CONSOLE_TRANCE redirects the trace console. To redirect it back to its original console, call the command again and specify NULL as the view parameter.
Example
redirectconsole(2, c);
buildnodeflexscript(getvarnode(Model.find("Processor1"), "exittrigger"));
redirectconsole(2, NULL);

This redirects the compiler console to the view c and then builds flexscript on a node in the model. Thus, any errors in building flexscript will be directed to the view c instead of to the compiler console.
redirectnetworktraveler (obj traveler, obj newdest)
Description
Attempts to change the end destination of the traveler to that of the newdest object. Only works if the traveler is currently on a TASKTYPE_TRAVEL task and is on a travel network. Returns 1 if successful.
Example
redirectnetworktraveler(traveler, Model.find("Processor5"));

Redirects the traveler to an object in the model named Processor5 assuming traveler is a pointer to a taskexecuter currently traveling on a network node system and Processor5 is connected to the network.

registereventtype (str name)
Description
Registers a custom event type for use with the Event Log. Returns the index of the eventtype to be used later by other commands such as logevent().
Example
int index = registereventtype("MyEventType");
releasebatch (node batch, int failed [, int/str/obj connector])
Description
Releases batch from a Batch activity. If failed is 1, all tokens in the batch will be released and the release quantity and label values will be ignored.
Example
releasebatch(batch, false);
releasebatch(batch, true, "Failed");
releasebatch(batch, true, getactivity(processFlow, "Garbage"));
releaseitem (obj flowitem [, num port ])
Releases the flowitem from its current object
Description
Releases the specified flowitem. A flowitem is released when it is free to exit the object currently containing it, at which time the Send to Port is evaluated. This command should only be used if the flowitem is in a BasicFR object and the flowitem has not been released already, or if it is any FixedResource and has been held with holditem().
The second paramter, port, is optional. If passed, the sendto will not be evaluated, but the item will instead be released out the specified port. If the flowitem exits, releaseitem will return 1. Otherwise it will return 0.
See also receiveitem() command.
Example
releaseitem(item)
releasetoken (node token [, int/str/obj connectorOrActivity])
Description
Deprecated. Use Token.release().
Example
releasetoken(token);
releasetoken(token, 3);

releasewave (node wave)
Description
Releases the wave from a Synchronize or Join activity.
Example
releasewave(wave);
relloc (obj object, obj containerobj, num coordinate)
Deprecated, use Vec3.project()
Description
This command is deprecated. Use Vec3.project() instead.

 This command returns the x, y, or z location of an object relative to an object that contains it. The containerobj does not need to be the immediate container, but does need to eventually be a container of the object. Use a coordinate value of 1,2,3 for x,y,z respectively.
Example
double x = relloc(current,model(),1);
double y = relloc(current,model(),2);
double z = relloc(current,model(),3);

Sets x, y and z to the x,y,z positions of the current object relative to the model space.

Description
For developer use. Set the report mode. (General or state.)
Example
reportmode(0);
repositionhighlightededits (obj view)
Description
For developer use. Repositions the edit controls for a tree view's highlighted object.
Example
requestoperators (obj dispatcher, obj station, obj involved, num nrofops, num priority, num preempting)
Description
Request a specified number of operators to come to the station object and work on the involved object until released. The involved object will later need to be passed into the freeoperators() command when releasing the operators. The operator(s) being called must either be the object referenced by dispatcher, or be connected to its output ports.

The tasksequence which is sent to the operator(s) will be given a priority and preempting value. The possible values for preempting are as follows:

    0 = PREEMPT_NOT
    1 = PREEMPT_ONLY
    2 = PREEMPT_AND_ABORT_ACTIVE
    3 = PREEMPT_AND_ABORT_ALL

 For each operater that needs to be called, stopobject() will be called on the station, and a tasksequence that looks like the following will be sent to the dispatcher (or operator) object.

    1. put a preempt "bookmark" in the task sequence (TASKTYPE_MILESTONE)
    2. travel to the station (TASKTYPE_TRAVEL)
    3. resume the station (TASKTYPE_STOPREQUESTFINISH)
    4. be utilized at the station (TASKTYPE_UTILIZE)
Example
requestoperators(current.centerObjects[1], current, item, 2, 0, PREEMPT_NOT);

This calls 2 operators connected to the object that is connected to the first center port of the current object to come to the current object, and work on the item.
rerankbesttask (obj object)
Description
This command forces the object specified as dispatcher to search through its task sequence queue and put the task sequence with the highest priority in the front of its queue. This will not reorder the other task sequences in the queue.
Example
rerankbesttask(current);
reset ()
Deprecated, use resetmodel()
Description
This command is deprecated. Use resetmodel() instead.

 For developer use. This command resets the model. The simulation clock is set to 0, and the OnReset event function is called for every object in the model. The OnReset events generally call the ResetTrigger functions that the users define. The model must be compiled before it can be reset. The resetmodel() command should typically be used instead of reset().
Example
reset();
go();
This resets then runs the model.
resetexperiment ()
Description
For developer use. Reset the experiment without performing a full model reset. It is typically used internally by the experiment manager.
Example
resetexperiment()
resetlayer (obj layer)
Description
For developer use. Resets the layer passed. Use resetmodel instead.
Example
resetmodel ([num buildflexscript])

Description
Resets the model. Use this command instead of reset(). The parameter specifies whether the engine should build all flexscript functions as well.
Example
resetmodel()
resetstats ()
Description
For developer use. Reset all object statistics without performing a full model reset. It is typically used internally by the experiment manager.
Example

resetuniqueid (obj flowitem)
Resets the uniqueid attributes on a flowitem to a value that has not been assigned to another flowitem
Description
This command resets the uniqueid attribute on a flowitem to a value that has not been assigned to another flowitem already. This attribute is required to collect Full History information for the Full Report. This command should be used if a flowitem has not been destroyed but needs to be considered as a new item for data collection purposes. For example, if a flowitem is being recycled by a modeler (not with the built-in recycling functionality), they should call this when the flowitem is returned to circulation. Flowitems typically only have the uniqueid attribute when Full History collection is enabled.
Example
resetuniqueid(item);
resumeanimation (obj object, num/str animation[, num resumeAtType, num resumeAtVal])
Deprecated, use Animation class
Description
This command is deprecated. Use the Animation class instead.

 Resumes an animation from some point in the middle of the animation.
Example
resumeanimation(current, "Stand");
resumeinput (obj object)
Deprecated, use Object.input.resume()
Description
This command is deprecated. Use Object.input.resume() instead.

 This command opens the input of an object just like openinput() does, but because it keeps track of previous stopinput() commands called on the object, it will only open input after all stops have been resumed. Refer to openinput() documentation for additional information.
Example
resumeinput(current.centerObjects[1]);
resumeobject (obj object [, num id, num stateprofile ] )
Deprecated, use Object.resume()
Description
This command is deprecated. Use Object.resume() instead.

 Tells the object that it may resume whatever it was doing before stopobject() was called on it.
The id value is optional and is for matching stop requests with resume requests. Refer to the stopobject()
documentation for more information on this.
Example
resumeobject(current.centerObjects[1]);
resumeoutput (obj object)
Deprecated, use Object.output.resume()
Description
This command is deprecated. Use Object.output.resume() instead.

 This command opens the output of an object just like openoutput() does, but because it keeps track of previous stopoutput() commands called on the object, it will only open output after all stops have been resumed. Refer to openoutput() documentation for additional information.
Example
resumeoutput(current.centerObjects[1]);
resumetransportsin (obj fixedresource [, num saverank])
Description
This should only be executed from triggers of a BasicFR object, and usually will only be executed from the resume object field. This command looks up references to taskexecuters that have been saved using the savestoppedtransportin command, and notifies those taskexecuters that they can resume their unload operation. The saverank parameter refers to a rank in the tree of a specific saved reference. If the saverank parameter is not specified, all saved references will be resumed. If this parameter is specified, only the taskexecuter associated with the specific rank will be allowed to resume. Saved references are stored as sub-nodes in the BasicFR's nroftransportsin variable. References to specific saved taskexecuters can be referenced by: nroftransportsinnode.subnodes[saverank].value
Example
resumetransportsin(current);
resumetransportsout (obj fixedresource [, num saverank])
Description
This should only be executed from triggers of a BasicFR object, and usually will only be executed from the resume object field. This command looks up references to taskexecuters that have been saved using the savestoppedtransportout command, and notifies those taskexecuters that they can resume their load operation.The saverank parameter refers to a rank in the tree of a specific saved reference. If the saverank parameter is not specified, all saved references will be resumed. If this parameter is specified, only the taskexecuter associated with the specific rank will be allowed to resume. Saved references are stored as sub-nodes in the BasicFR's nroftransportsout variable. References to specific saved taskexecuters can be referenced by: nroftransportsoutnode.subnodes[saverank].value
Example
resumetransportsout(current);
return (num value)
Description
This command causes a function to stop executing and return value to the function that called it.
Example
double res = item.rank * 5;
return res;

 This sets the value of res to 5 times the rank of the item referenced by item. The value stored in res is then returned to the function that called this one.
richeditaddtext (obj richedit, str text, num protected (0/1))

Deprecated, use Math.round()
Description
This command is deprecated. Use Math.round() instead.

 Rounds the value to the nearest integer.
Example
rundocument (str command, str path+filename)
Open a file using the default application for the file type
Description
Opens a file using the default application used for opening files with the specified extension on your computer. The available commands are: edit, explore, find, open, and print. A return value > 32 means success.
Example
rundocument("open","C:/myfile.doc");

 Opens myfile.doc with whatever application is default for opening *.doc files on your computer.
runexpertfit ()
Description
For developer use. Starts the expertfit program automatically if licensed.
Example
runexpertfit()
runfunction ()
Description
For developer use. Block user input/output, perform a model run at maximum speed possible by cpu, and return control when stoptime is met. If stoptime = 0, the stoptime is assumed to be 1000. See go().
Example
runfunction()
runprogram (str commandline)
Run an external program
Description
Run an external program. This command will issue a command to the operating system. The commandline may contain full program arguments. A return value > 31 means success.
Example
runprogram("c:/myprogram.exe")
runspeed (num speed[, num precisionMode])
Sets the simulation speed
Description
This command sets the speed at which the simulation will run. It is the same as clicking and dragging the slider bar on the Run Control window, but more precise. The speed that the model will attempt to run at is defined as the number of simulation time units per real second. The model may not actually achieve this speed if the computer cpu can not keep up. precisionMode defines the precision to use. If 0, the precision mode will remain what it was before the call. If you pass RUN_SPEED_LOW_PRECISION, it will set to a low precision run speed. If you pass RUN_SPEED_HIGH_PRECISION, it will run in high precision mode. This is used for emulation purposes. The precision mode will be reset to low precision on every reset, so you need to have something in your model set it back on reset or when the model starts to enable high precision mode.
Example
runspeed(10);
go();

 This sets the speed to 10 simulation seconds per real second, then runs the model.
savebyname (obj tree, str filename)
Description
For developer use. Saves the specified tree node to a file with the given name.
Example
savebyname(Model.find("MyProcessor"), "C:\\MyProcessor.t");
savefpk (node servicepackhead)
Deprecated, use user libraries
Description
This command is deprecated. Use user libraries instead.

 This saves the node to disk as a service pack file (.fpk).
A save file dialog box will appear, allowing you to define the path and name of the file. A service pack is nothing more than a node with subnodes. The first subnode is assumed to be toggled flexscript and contain string data with code. When the service pack is loaded using File | Install Service Pack, the first subnode of you service pack will execute automatically. The code will usually copy the other subnodes into the MAIN and VIEW trees.
Example
savefpk(so());
savemodelprepare ()
Description
For developer use. Prepares the model to be saved, including reseting, etc.
Example
savemodelprepare();
saveselectedtofile ()
Description
For developer use. Saves all selected objects in the model to a tree file.

Example
savestate();
savestoppedtransportin (obj fixedresource, obj taskexecuter)
Description
This should only be executed from the transport in complete trigger of a BasicFR object.
If the BasicFR is not ready to receive an item that a taskexecuter is about to unload, it must save off a reference to the taskexecuter, then return the value -1.
The taskexecuter will then go into a blocked state and wait until the BasicFR is ready to receive it. When the BasicFR becomes ready to receive the item(s), it should call the resumetransportsin() command.
This will look up saved references and notify their corresponding taskexecuters that they can immediately resume their unload operation.
Example
if(getvarnum(current, "nrofstops") > 0)
{
savestoppedtransportin(current, transporter);
return -1;
}
savestoppedtransportout (obj fixedresource, obj taskexecuter)
Description
This should only be executed from the transport out complete trigger of a BasicFR object.
If the BasicFR is not ready to send an item that a taskexecuter is about to load, it must save off a reference to the taskexecuter, then return the value -1.
The taskexecuter will then go into a blocked state and wait until the BasicFR is ready to send the item. When the BasicFR becomes ready to send the item, it should call the resumetransportsout command.
This will look up saved references and notify their corresponding taskexecuters that they can immediately resume their load operation.
Example
if(getvarnum(current, "nrofstops") > 0)
{
savestoppedtransportout(current, transporter);
return -1;
}
savetree (node tree, str extension, str description, str startingpath)
Description
For developer use. Opens a save file dialog prompting the user for a file name to save. The tree passed in will be saved with the specified name, unless a session is selected. Then the first parameter is ignored. cdir() and pdir() may not be directly used as the path in FlexScript.
Example
savetree(model(),"fsm","FlexSim Model",documentsdir());
scalekinematicstotime (node kinematics, int kinematicnr, double scaletotime)
Scales the kinematics to a defined time
Description
Scales the kinematic(s) to a defined time. This can be used to preserve the characteristics of the kinematics, i.e. accelerate->peak speed->decelerate, but have the total time it takes to perform the kinematics be defined by some other mechanism such as a distribution. If kinematicnr is 0, then the entire set of kinematics will be scaled to the given time. If kinematicnr is greater than 0, then only that kinematic will be scaled. The return value is the new end time of the kinematic(s).
Example
scalekinematicstotime(kinematics, 0, exponential(0, 10));
scrollinfo (obj/HWND view, num get_set {0-1}, num horz_vert_ctl {0-2}, num scrollinfo {1-4}[, num value])
Description
For developer use. Gets or sets scrollinfo for a scrollbar on a view. The value parameter is only used if get_set is 1. The position of the scrollbar (nPos) is changed with scrollinfo 4. You can also get and set the nMin, nMax, and nPage values of the scrollbar with scrollinfo 1, 2, and 3 respectively.
Example
scrollinfo(TheTable,1,1,4,scrollinfo(c,0,1,4)-amount);
searchdata_n (obj startnode, num val)
Description
For developer use. Search for a number data match under startnode. Only number data nodes are searched. Results appear on the output console. Returns the total number of matches found.
Example
searchdata_n(main(),25)
searchdata_s (obj startnode, str string [, num replication])
Description
For developer use. Search for a string data match under startnode. Results appear in the output console. This function will recognize substrings and report which nodes contain them, and how many. The search is case-sensitive. Replication is currently not used. Returns the total number of matches found.
Example
searchdata_s(main(),"glVertex()",1)
searchfornode (str/node searchstr, node startnode, num findnr[, num searchobjects])
Description
For developer use. Recursively searches the startnode for a node with a name containing the searchstr. The findnr parameter is useful when the search finds multiple nodes containing the given name, specifying a number i here will give you the ith node found. Set searchobjects to 1 to search the object's data nodes.
Example
searchname (obj startnode, str searchname)
Description
For developer use. Search for a name match under startnode. Results appear in the output console. The search is case-sensitive. Returns the total number of matches found.

senddelayedmessage (obj toobject, num delaytime, obj fromobject [, num par1, num par2, num par3])
Send a delayed message to an object, firing its OnMessage trigger after the delay time has transpired
Description
Causes a message to be sent to the toobject from the fromobject after the delaytime has transpired. When the toobject receives the message, its OnMessage trigger will fire.
In the code of the OnMessage trigger, you may refer to the fromobject as msgsendingobject, and the three numeric par values passed in as msgparam(1), msgparam(2) and msgparam(3).
This is a very usefuly command for creating your own time events during a model run.
Example
senddelayedmessage(current.outObjects[1], 25, current, 0, 0, 0);

Sends a message from the current object to the object connecte to output port 1 of the current object 25 time units after this command is executed. Zeros are passed for all three of the user-defined parameters.
sendmessage (obj toobject, obj fromobject [, var par1, var par2, var par3])
Send a message to an object, firing its OnMessage trigger
Description
Causes a message to be sent immediately to the toobject from the fromobject as in a direct function call. When the toobject receives the message, its OnMessage trigger will fire.
In the code of the OnMessage trigger, you may refer to the fromobject as msgsendingobject, and the three par values passed in as msgparam(1), msgparam(2) and msgparam(3). These message parameters are Variants, meaning they can be numbers, strings, treenode references or arrays.
Example
sendmessage(current.centerObjects[1], current, item, 10);

 This sends a message to the object connected to current's first center port. A reference to item is passed as par1 and the number 10 as par2.
sendonactivatenotify ()
Description
For developer use. Causes each palette windows' OnActivateNotify event to fire.
Example
sendonactivatenotify();
sendwindowmessage (HWND window, num msg[, num/str/node wParam, num/str/node lParam])
Description
For developer use. This gives direct access to the Windows API SendMessage() command, sending a message to a window. Use windowfromnode() or getviewhwnd() to get access to the window handle. Refer to Windows API documentation for more information. Not that you cannot use a message that uses lParam or wParam as an [out] parameter, or one that you pass in as a pointer to a struct. You should be able to pass strings into lParam or wParam, but again thay cannot be [out] parameters. FlexSim does not include all possible WM_ messages in its flexscript macros, so if you want to use one in flexscript, you will need to find the definition in the windows header files and add the definition to your flexscript code.
Example
sendwindowmessage(windowfromnode(view), WM_COPY, 0,0);
serveraccept (int noblocking)
Gets the server will attempt to accept a client connection
Description
The server will attempt to accept a client connection. If noblocking = 0, the command blocks until a connection is made. It returns an index used to reference the connection made.

The server will attempt to accept a connection from a waiting client. A number will be returned that is the index of the connection established. A return value of 0 indicates that no connection was created. This value will be used in all future server calls. If noblocking = 1, the server will not block FlexSim program execution, but will return a 0 if no client attempts to connect. If noblocking = 0, the server will block (freeze) FlexSim program execution until a client attempts to connect. Connections with clients are only made with this command.
Example
int client = serveraccept(0);
servercloseconnection (int connection)
Closes the client connection
Description
The specified connection to a client is closed. Does not close the main server socket. This should be done when the server is completely finished communicating with a client.
Example
servercloseconnection(1);
serverclosemain ()
Closes the main server socket and all open connections
Description
Closes the main server socket and all of the connections that are still open. No more communication can be done until it is created again. All connections should be closed before this is called.
Example
serverclosemain()
servercreatemain (int port)
Creates a server socket that is listening for connections to the specified port
Description
Creates a server socket that is listening for connections on the specified port. Some ports (called well-known ports) are reserved for special applications. Anything port number over 1024 is usually safe to use.
Example
servercreatemain(1880);
serverreceive (int connection, char *buffer, int bufsize, int noblocking)
Receives a message from the connection
Description
Receives a message from the specified connection. This command operates differently in flexscript vs. c++. In c++, buffer must be a valid pointer to a char* destination into which the read bytes will be copied. The return value will be the total number of bytes received. Up to bufsize bytes from the clients message will be read and stored in the preallocated character array called buf. In flexscript, however, buffer should be passed as NULL, and the return value will be the actual string that is received. If noblocking = 1, then this command does not block FlexSim program execution, but if noblocking = 0, FlexSim program execution will block (freeze) until something is received from the client.
Example
c++: int bytes = serverreceive(1,Buf,15,0);
flexscript: string readstr = serverreceive(1, NULL, 15, 0);
serversend (int connection, char* message [, num charlength] )
Sends a message to the client connect to connection
Description
Sends the specified text message to the client that is connected to the specified connection. Returns the number of bytes (characters) sent correctly. The text message to be sent must be converted into a char *. The charlength is the length of the string being passed and is usually optional. Needed only if the string being sent has NULL characters in it.
Example
serversend(1,"MadeConnection");
set (node thenode, num value)
Deprecated, use treenode.value
Description
This command is deprecated. Use treenode.value instead.

 Sets the value of a node with numeric data.
Example
setanimationvar (obj object, num/str animation, str varName, num/obj toValue)
Sets the value of an animation variable on an object
Description
Sets the value of an animation variable on an object. Animation variables are attributes of an animation that may need to dynamically change for different runs of the animation, such as surrogates, time between keyframes, or position/rotation/size values of a given keyframe. For example, you may use surrogates in building your animation. You do this by choosing a default visual from the flowitem bin to use as you create the animation. Then when the simulation runs, you substitute real flowitems in for those surrogates when you run the simulation. You do this substitution by setting the value of an animation variable that you've associated with that surrogate to the actual reference to the flowitem. Another example is you may use an animation variable to dynamically define the z position of a keyframe at run-time.
Example
setanimationvar(current, "Animation1", "Item1", current.first);
setapplicationtitle (str title)
Description
For developer use. Sets the current application's title.
Example

setbundlevalue (node datanode, num entrynr, str/num field, num/str val)
Sets the value of the entry (base 0) and field (base 0) of the bundle
Description
Sets the value of the defined entry (base 0) and field (base 0) of the bundle.
Example
setbundlevalue(x, 5, "Object Name", current.name);
setcameradirection (obj view, num x, num y, num z, num rx, num ry, num rz)
Sets the viewpoint direction of the 3D view
Description
Set the viewpoint direction of an orthographic or perspective view. (x,y,z) is the location of the focus point of the camera. (rx, ry, rz) is the rotation of the camera. The associated view attribute names are: viewpointx, viewpointy, viewpointradius, viewpointrx, viewpointry, viewpointrz respectively.
Example
setcameradirection(sv(), 0, 0, 0, -40, 0, 25);
setcameravolume (obj view, num w, num h, num nearclip, num farclip, num magnification, num fov, num projtype, num firstperson)
Description

Example
setchecked (obj view, num value)
Description
For developer use. Set the checked state of a button.
Example
setchecked(c,0) ;
setcollisioncheck (obj taskexecuter, num checkstate [, num checkinterval])
Sets the state and interval for collision checking on the taskexecuter
Description
Sets the state and interval for collision checking on the taskexecuter. If checkstate is 1, then check for collisions, else don't. If interval is >0, then reset the "Time between Collision Checks" for the taskexecuter specified.
Example
setcollisioncheck(traveler,1,5);

Starts the traveler checking for collisions every 5 time units.
setcolor (obj object, num red, num green, num blue)

Example
setcursor(3)
setdrawnamefunction (num boxwidth, num boxheight, node nodefunction[, num pval1, num pval2, num pval3])
Description
This command gives direct access to the functionality that displays information in boxes below objects in the model. FlexSim's 3D display mechanism works by performing multiple drawing passes over the objects in the model. First, it gathers and caches data for what needs to be drawn. Then it goes through and draws the object shapes and calls the objects' custom draw functionality. Finally it draws any overlays such as connectors, information boxes, etc. The setdrawnamefunction() command, if called as part of an object's custom draw functionality, i.e. its OnDraw event or its Custom Draw Code trigger, will cause a callback to be fired when the drawing sequence gets to the information box step for that object. To do this, call the command and specify the size that you want the box to be drawn, and pass as the nodefunction parameter a reference to a node holding the code you want to fire to draw the box information, as well as up to 3 parameters that will be passed as param(1), param(2), and param(3) into that nodefunction. Then implement the nodefunction code to draw any information you want, using the drawflattext() command, or any other OpenGL drawing commands. Note that when the nodefunction is call, the OpenGL model view matrix will be set so that the (0,0,0) point is at the top-center of the display box, and one length unit represents one pixel on the screen.
Example
Add the following code to an object's Custom Draw Code trigger: 

if(!param(2)) {
	setdrawnamefunction(80, 15, c, param(1), 1);
} else {
	fglTranslate(-40, -15, 0);
	drawflattext("Hello World");
}
This will draw the text Hello World in the display box below the object
setdropcoords (obj view[, obj dropnodefrom, obj dropnodeto])
Description
For developer use. Sets the dropx() and dropy() coordinate commands for the view based on current mouse location. You can optionally also set the dropnodefrom and dropnodeto parameters, which will define the nodes returned by dropnodefrom() and dropnodeto().
Example
setdropcoords()
seteventtime (str EventName, num time, num timemode[1/2], num createevent[1/0])
Sets the "Repeat Event Time" for the global UserEvent
Description
Sets the "Repeat Event Time" for the specified global UserEvent. If timemode = 1, then timeval will be used directly; otherwise, the timeval - time() will be used. If createevent = 1, then in addition to updating the "Repeat Event Time", a single event will be created at the previous time specified.
Example
seteventtime("UserEvent1",20,1,0);

The global userevent named "UserEvent1" will have its "Repeat Event Time" to 20.
setframe (obj object, num/str toframe)
Sets the shape frame of an object
Description
Sets the frame attribute of the object to the framenumber. The frame defines which 3D image to display. This is a nice way of changing the 3D shape of an object on the fly. There are two ways to define frames on an object. First, you can do it through the naming of various 3D files. For example, if the object was assigned Operator.3ds as its default shape, and there are additional files in the same directory as Operator.3ds named OperatorFRAME1.3ds, OperatorFRAME2.3ds and OperatorFRAME3.3ds, then the frame attribute could be set to 0,1,2, or 3 which would change the displayed shape to each of the 3ds files respectively. Secondly, you can add sub-nodes to an obejct's shape attribute, each with a path to the 3D file associated with that frame. Subsequently, frame 1 would be associated with the shape attribute's first sub-node, etc. This is the method used within FlexSim's environment to define shape frames. If toframe is a string, then the latter method is assumed, and it will find the shape attribute sub-node with the corresponding name. One use of this command would be to change the 3d shape in the OnDown trigger to show a "broken" shape.
Example
if(getframe(current) == 3)) setframe(current, 5);
setitem (thing)
Deprecated do not use
Description
This command is deprecated. Do not use.
Example
setiteminvolved (obj item, obj involved)
Description
This sets the object reference stored in the FixedResource involved variable for the item. The FixedResource class allows sub-classes to store 1 involved variable on each flowitem. What these variables mean is dependent on the type of class. For example, a Processor uses the involved variable to store a reference to the dispatcher called for a flowitem if the Processor is set to use operators for the process or setup time. Only use this command if you are using the explicit FixedResource class as and object in your model. You can use this command, along with the setitemvar, getitemvar, and getiteminvolved commands, to store variables on the items the object receives.
Example
setiteminvolved(current.first, current.centerObjects[1])
setitemsendto (obj item, num value)
Description
This sets the value of the sendto for the item if it is in a FixedResource. Only use this command if you are using an explicit FixedResource class object and want to store a sendto value on the item before releasing it, and then later use the releaseitem() command, passing the port in. If you want to change the evaluated sendto of an item that has already been released, execute holditem(), and then releaseitem() again, instead of this command.
Example
setitemsendto(item, current.currentsendto)
setitemtype (obj object, num value)
Deprecated, use labels
Description
This command is deprecated. Use labels instead.

 This command sets the itemtype attribute of the object to value. If the object does not have the itemtype attribute, this command does nothing. The attribute itemtype is typically used to distinguish between different types of flowitems that may be of the same class.
Example
setitemtype(item,duniform(1,3));

This sets the itemtype attribute of the flowitem referenced by item to a random integer between 1 and 3.
setitemvar (obj item, num var, num value)
Description
This sets the value of a FixedResource variable for the item. The var parameter should be either 1, 2, or 3, and the value parameter should be whatever value you want to set it to. The FixedResource class allows sub-classes to keep up to 3 number variables on each flowitem. What these variables mean is dependent on the type of class.

 For example, a Processor uses variable 1 to store the time the item started its processing time, and variable 2 to store the item's processing time. If you are using the explicit FixedResource class as an object in your model, you can use this command, along with the getitemvar, getiteminvolved, and setiteminvolved commands, to store variables on the items the object receives.
Example
setitemvar(current.first, 3, time())
setkinematicsrotoffset (node infonode, num rx, num ry, num rz)
Description
Sets the initial kinematics rotational offset for a kinematics operation. For more information, refer to the help documentation on kinematics.
Example
setkinematicsrotoffset(current.labels["kinematics"], 0, 0, 180);
setlabel (obj node, str/num label, num/str/node value)
Deprecated, use treenode.LabelName
Description
This command is deprecated. Use treenode.labelProperties instead.

 Sets the value of an object's label.
Example
setlabelnum (obj object, str/num label, num value)
Deprecated, use treenode.LabelName
Description
This command is deprecated. Use treenode.labelProperties instead.

 Sets an object label value.
Example
setlabelstr (obj object, str/num label, str value)
Deprecated, use treenode.LabelName
Description
This command is deprecated. Use treenode.labelProperties instead.

 Sets an object label value
Example
setloc (obj object, num x, num y, num z[, num xFactor, num yFactor, num zFactor])
Deprecated, use Object.location
Description
This command is deprecated. Use Object.location instead.

 Sets the x, y, and z location of the object relative to its container.
Example
setmessageloopsleep (num interval, num sleeptime)
Description
For developer use. Set a sleep time for each cycle of the message loop to decrease cpu load. Use carefully because a large value can make FlexSim unresponsive to user input. Every interval milliseconds, FlexSim will pause for a period of sleeptime milliseconds. This command may help certain laptops that tend to overheat due to excessive cpu usage.
Example
setmessageloopsleep(1)
setname (obj object, str value)
Deprecated, use treenode.name
Description
This command is deprecated. Use treenode.name instead.

 Sets the name of a node/object.
Example
setnodename (obj/node object, str value)
Deprecated, use treenode.value
Description
This command is deprecated. Use treenode.name instead.

 Sets the name of a node/object.
Example
setnodenum (node thenode, num value)
Deprecated, use treenode.value
Description
This command is deprecated. Use treenode.value instead.

 Sets the value of a node with numeric data.
Example
setnodestr (node thenode, str value)
Deprecated, use treenode.value
Description
This command is deprecated. Use treenode.value instead.

 Sets the value of a node with string data.
Example
setobjectbillboard (obj object, num mode)
Sets the billboard attribute of the visual tool object
Description
This command sets the billboard attribute of the visual tool object. The following modes are available:
0: No Billboard, the visual tool will display based on its set rotation.
1: Vertical Billboard (plane only), this will cause the plane to stand vertically in the model and always face toward the camera along the same viewing plane.
2: All Around Billboard (plane only), this will cause the plane always present its face to you no matter what the viewing angle is.
3: Screen Locked Billboard, locks the Visual Tool in front of the view.
Example
setobjectbillboard(current, 1);
setobjectimageindex (obj object, num index)
Deprecated, do not use.
Description
This command is deprecated. Do not use.

 Sets the index number of the bmp or jpeg image to be assigned to the base of the object (2D shape and base image). For the new index to take effect, the imagebase node of the object must be removed or renamed, so this command renames the imagebase node to "_imagebase" for you. The index number must be a valid index number of a currently imported bmp or jpeg image. To view currently imported images, or to import another bmp or jpeg image, use the Import Media option in the ToolBox.
Example
setobjectimageindex(item,gettextureindex("fs3d\\BBsphere.bmp"));
setobjectshapeindex (obj object, num index)
Sets the index number for the 3D shape of an object
Description
Sets the index number for the 3D shape of an object. For the new index to take effect, the shape node of the object must be removed or renamed, so this command renames the shape node to "_shape" for you. The index number must be a valid index number of a currently imported 3D shape. To view currently imported 3D shapes and to import more shapes, use View -> Media Files. See setframe() as another solution to changing the 3D shape of an object on the fly.
Example
setobjectshapeindex(item,getshapeindex("fs3d\\Processor.3ds"));
setobjecttextureindex (obj object, num index)
Sets the index number of the image assigned as a texture for the object's 3D shape
Description
Sets the index number of the bmp or jpeg image to be assigned as the texture for the object's 3D shape. The index number must be a valid index number of a currently imported bmp or jpeg image. To view currently imported images, or to import another bmp or jpeg image, use the Import Media option in the ToolBox. Note that this command does not change the object's imageobject attribute so the original texture will return when the model is reset.
Example
setobjecttextureindex(item,gettextureindex("bitmaps\\flowitempicture.bmp"));
setpickingdrawfocus (obj theview, obj focus, num what[, obj secondaryfocus, num flags])
Description
For developer use. Sets the draw code following this call to be picked as the focus when clicking or dragging. Usually you would use this to draw custom sizers and grippers on your object, and then implement an OnDrag or an OnClick event on the object that would call getpickingdrawfocus() to figure out what part was clicked.
flags is a bitwise combination of one "DETECT_DRAG" setting, as well as optional "override" bits. The override bits aren't used to define picking focus, but will cause FlexSim to override its normal drawing of sizers and bounding boxes.
DETECT_DRAG_X, DETECT_DRAG_Y, DETECT_DRAG_Z - will only detect dragging along the given axis, relative to the object being drawn. Use this with the draginfo() command in your OnDrag event to determine where the object is being dragged.
DETECT_DRAG_XY, DETECT_DRAG_YZ, DETECT_DRAG_XZ - will only detect dragging along the given plane. Again you would use this with the draginfo() command in the OnDrag event.

 OVERRIDE_DRAW_SIZER_X, OVERRIDE_DRAW_SIZER_Y, OVERRIDE_DRAW_SIZER_Z, OVERRIDE_DRAW_SIZER_X_NEG, OVERRIDE_DRAW_SIZER_Y_NEG, OVERRIDE_DRAW_SIZER_Z_NEG, OVERRIDE_DRAW_SIZER_ALL - these flags will cause the engine to not draw the flagged sizers
OVERRIDE_DRAW_YELLOW_BOX - causes FlexSim to not draw the yellow box around the object when selected
OVERRIDE_DRAW_GREEN_BOX - causes FlexSim to not draw the green "statistics-active" box around the object
OVERRIDE_DRAW_REDBOX - causes FlexSim to not draw the red selection box around the object when selected
OVERRIDE_DRAW_HOVERBOX - causes FlexSim to not draw the yellow hover box around the object when hovering over it
OVERRIDE_DRAW_ALL - causes FlexSim to not draw any sizers or boxes around the object

OVERRIDE_SET_MOUSE_DOWN_PICK - explicitly sets the view's "mouse down" pick to the defined values. This is called outside of the drawing sequence, and updates the pick information "as-if" the mouse had been pressed on the given object.
OVERRIDE_SET_MOUSE_DOWN_PICK - explicitly sets the view's "mouse up" pick to the defined values. This is called outside of the drawing sequence, and updates the pick information "as-if" the mouse had been released on the given object.
OVERRIDE_SET_MOUSE_MOVE_PICK - explicitly sets the view's "mouse move" pick to the defined values. This is called outside of the drawing sequence, and updates the pick information "as-if" the mouse had been moved on the given object.
OVERRIDE_SET_MOUSE_HOVER_PICK - explicitly sets the view's "mouse hover" pick to the defined values. This is called outside of the drawing sequence, and updates the pick information "as-if" the mouse had been hovered over the given object.

This command will return the index corresponding to the loaded sound. Microsoft Wave Format files (.wav) can be loaded and played. Sounds can have their volume, balance and frequency adjusted dynamically. Multiple channels are managed through the Microsoft DirectSound Interface.
Example
int applauseindex = soundload("c:/My Music/APPLAUSE.WAV");
soundplay (obj view, num soundindex, num volume [, num tempo, num repeat y/n, num balance])
Play a loaded sound
Description
Play a loaded sound. Sounds are attached to a window by the operating system, so the view parameter is important. To get the soundindex use getsoundindex(). The volume, tempo and balance are numbers between 0 and 1. To continuosly repeat the sound, use a repeat of 1 else 0.

This command will set the values to be returned by subsequent calls to the splinex(), spliney(), splinez(), splinerx(), splinery(), splinerz(), splinelength(), splineposobject() commands. It will not set the precalculated values for the spline object given in spline, as in fastspline().The parameter perc is the position along the spline of interest. This command does not lock precalculated values as when the fastsplineall() or fastsplineupdate() commands are used. A spline can be defined as any chain of objects that are connected from output ports to input ports. Pass the first object in the output port to input port chain as parameter 1.
Example

startlisten (obj listener)
Description
For developer use. Tell the executive that an object is a listener. Not persistent across sessions. This command will add a node in the executive listener list pointing to listener. When a session is reloaded, or after a compile, listeners need to be reset. The listening mechanism can add a significant load to the executive, so use minimally. Listeners will receive OnListen messages when an event (OnTimerEvent) is dispatched to any object in the model. The listener must filter the message to decide whether to respond to the OnListen message. Refer to the Online Reference Guide for the parameters passed into an OnListen message.
Example
startlisten(so())

Example
step()
stick (num stickno, num command [, HWND/num win, var/num p])
Description
For developer use. This command queries the joystick or controller state or sets functionality for a joystick or controller.

stickno defines an id for the joystick or gamepad you want to query. This is a number between 0 and 32. Usually you will only have one joystick connected to your computer, so in this case you should use the value 1 as stickno. If you are using a gamepad, you might need to use stickno 2. For Xbox controllers, stickno will be a value between 0 and 3. For VR controllers, stickno will be either 0 or 1. For Oculus touch controllers, stickno 0 is the left hand and stickno 1 is the right hand. Use stickno -1 to get the status, position, or rotation of a connected VR headset.

command defines the operation that the command should perform. This should be one of the macros below:

STICK_JOY_STATUS - Queries the connectivity of the joystick. If the joystick is connected properly, then this command will return 0. If the return value is non-zero, then there is some error with the joystick's connectivity, and you can view the system console to see what the error is. The following errors apply:
    MMSYSERR_NODRIVER - The joystick driver is not present.
    MMSYSERR_INVALPARAM - Invalid joystick ID or hwnd is NULL.
    JOYERR_NOCANDO - Cannot capture joystick input because a required service (such as a Windows timer) is unavailable.
    JOYERR_UNPLUGGED - The specified joystick is not connected to the system.
    JOYERR_PARMS - Invalid joystick ID or hwnd is NULL.

STICK_JOY_XPOS - Current X-coordinate of the joystick. This is a number between 0 and 65535. 0 means the joystick is pushed all the way to the left, 65535 means it is pushed all the way to the right, and 32768 is exactly in the center. If you are using a gamepad, then this is the x position of the left side joystick.

STICK_JOY_YPOS - Current Y-coordinate of the joystick. Again this is a number between 0 and 65535. 0 is up, 65535 is down. If you are using a gamepad, this is the position of the gamepad's left joystick.

STICK_JOY_ZPOS - Current Z-coordinate of the joystick. If you are using a joystick, this will usually be the current setting of the joystick's throttle. Again it is a value between 0 and 65535. If you are using a gamepad, this represents the y position of the right side joystick.

STICK_JOY_BUTTONS - Current state of the 32 joystick buttons. This is bitwise integer with each bit representing the state of a given button. For a joystick, the main trigger button is usually represented by the 0x00000001 bit, other buttons on the stick are 0x00000002 and 0x00000004, and buttons on the base of the joystick are then higher order bits. You will need to test these out on your own as each joystick is a little different.

STICK_JOY_SET_CAPTURE - This command sets the joystick capture to a FlexSim window that you specify. This command requires the win and p parameters to be passed in. By executing this command, joystick messages will be sent to the OnStick attribute of the view. For example, if you have an ortho view that you would like to listen to joystick events, you would call this command, passing the ortho view's HWND handle (use windowfromnode()), and a polling period. The period specifies a time interval in milliseconds to repeatedly call the OnStick event. If p is 0, then the OnStick event will only be called when the joystick's state changes. If p is greater than 0, then the OnStick event will simply be called at the end of each sample period interval. Example: stick(1,5, windowfromnode(sv()), 200); This will cause the OnStick event to be called every 200 milliseconds. In order for this to work, you need to add an OnStick attribute to the view (you may also need to rebind the view's attributes after adding it: right-click->Edit|Rebind Object Attributes).

STICK_JOY_RELEASE_CAPTURE - This command releases the joystick capture for the window that was previously captured with the 5 command. You need to pass in the win parameter as with command 5.

STICK_JOY_RPOS - Current position of the rudder or fourth joystick axis of the joystick. For a joystick, this is usually the rotation of the joystick if your joystick can rotate around its z axis. Again it is a number between 0 and 65535. If you are using a gamepad, it is the x position of the right side joystick.

STICK_JOY_UPOS - Current fifth axis position of the joystick.

STICK_JOY_VPOS - Current sixth axis position of the joystick.

STICK_JOY_POV - Current position of the point-of-view control of the joystick. It is a number between 0 and 35900 and represents the number of degrees times 100. For a gamepad, this represents the directional pad on the left of the gamepad. Up is 0, right is 9000, down is 18000, left is 27000. If the directional pad is not pressed, the value will be 65535. If you are using a joystick, there may be a directional thumb controller on the stick itself that you can press up, down, right, or left, and this will get the setting of that controller.

STICK_JOY_CURRENT_BUTTON - Current button number that is pressed.

STICK_JOY_FLAGS - Flags indicating the valid information returned about the joystick.

STICK_XBOX_STATUS - Queries the connectivity of the Xbox controller. If the controller is connected properly, this returns 0.

STICK_XBOX_BUTTONS - Bitmask of the device digital buttons. A set bit indicates that the corresponding button is pressed.

STICK_XBOX_LEFT_THUMB_X - Left thumbstick x-axis value. Each of the thumbstick axis members is a signed value between -32768 and 32767 describing the position of the thumbstick. A value of 0 is centered. Negative values signify down or to the left. Positive values signify up or to the right.

STICK_XBOX_LEFT_THUMB_Y - Left thumbstick y-axis value. The value is between -32768 and 32767.

STICK_XBOX_RIGHT_THUMB_X - Right thumbstick x-axis value. The value is between -32768 and 32767.

STICK_XBOX_RIGHT_THUMB_Y - Right thumbstick y-axis value. The value is between -32768 and 32767.

STICK_XBOX_LEFT_TRIGGER - The current value of the left trigger analog control. The value is between 0 and 255.

STICK_XBOX_RIGHT_TRIGGER - The current value of the right trigger analog control. The value is between 0 and 255.

STICK_VR_STATUS - Returns 1 if an Oculus Rift controller is active. Returns 2 if an HTC Vive controller is active. Returns 0 if the controller is inactive. Returns nullvar if the controller is not attached.

STICK_VR_THUMB_X - Thumbstick or trackpad x-axis value between -1 and 1.

STICK_VR_THUMB_Y - Thumbstick or trackpad y-axis value between -1 and 1.

STICK_VR_INDEX_TRIGGER - Index trigger value between 0 and 1.

stop ([num fast])
Stops the simulation run
Description
This command stops the simulation clock from running. The model stops with all of its pending events still in the queue. If the user starts the model again before resetting, the model will continue from the exact time that it stopped at. If fast is 1, then FlexSim will not rebind objects. This will improve speed if you are stopping and starting often.
Example
stop()
stopanimation (obj object, num/str animation)
Deprecated, use Animation class
Description
This command is deprecated. Use the Animation class instead.

 Stops an animation on an object.
Example
stopanimation(current, "Walk");
stopinput (obj object)
Deprecated, use Object.input.stop()
Description
This command is deprecated. Use Object.input.stop() instead.

 This command closes the input of the object just like closeinput() does, but it also keeps track of consecutive stopinput() commands, and will only open input after all stops have been resumed. Refer to closeinput() documentation for additional information.
Example
stopinput(current.centerObjects[1]);
stoplisten (obj listener)
Description
For developer use. Tell the executive that this object is not a listener anymore. This command will remove the pointer to listener from the listeners list if previously added with the startlisten() command. Listeners will receive OnListen messages when an event (OnTimerEvent) is dispatched to any object in the model.
Example
stoplisten(so())
stopobject (obj object, num state [, num id, num priority, num stateprofile] )
Deprecated, use Object.stop()
Description
This command is deprecated. Use Object.stop() instead.

 Tells the object to stop whatever it is doing, go into the state specified (in the state profile if specified), and waits for resumeobject() to be called. Stopobject commands are accumulated, meaning if stopobject is called twice on the same object, the object will not resume its operations until resumeobject has been called twice as well. Stopping an object depends on the type of object that is being stopped.

For FixedResources, generally events are delayed indefinitely, input and output is stopped, and all operations going into and out of the object are stopped. This means that TaskExecuters trying to load/unload to or from the object will have to wait until the object has been resumed.

For TaskExecuters, events are not delayed, but rather a preempting task sequence with priority of 100,000 is created for the TaskExecuter, with one TE_STOP task in it.

Be aware that, if there are several stop requests for the same object, the state for each stop request is not remembered. If an object is requested to stop by entity A with state 12, and then is later requested to stop by entity B for state 14, it will go into state 14 and forget state 12. Even if entity B resumes the object before entity A, the object will remain in state 14 until all stop requests have resumed.

The last two parameters, id and priority, are optional and have recently been added to fix the problem in the previous paragraph. If you specify these parameters, then it will store a record of the stop request, instead of just incrementing a value for the number of stops requested. The id is like a key for that stop request. The priority allows the object to prioritize its stop requests. For example, if you have a stop request for the scheduled down state, and another for the breakdown state at the same time, technically the object should be in two states at once, but since a FlexSim object can only be in one state at a time, the priority value breaks the tie and goes into the state of the highest priority stop request.

The id value should match an id value that is added to a resumeobject() command later on. This is for matching stop requests with their appropriate resume requests. For example, if you stop an object for scheduled maintenance with and id of 1, once the scheduled maintenance is finished, you will need to resume the object with the same id of 1.
Example
stopobject(current.centerObjects[1], STATE_BLOCKED);
stopoutput (obj object)
Deprecated, use Object.output.stop()
Description
This command is deprecated. Use Object.output.stop() instead.

 This command closes the output of the object just like closeoutput() does, but it also keeps track of consecutive stopoutput() commands, and will only open output after all stops have been resumed. Refer to closeoutput() documentation for additional information.
Example
stopoutput(current.centerObjects[1]);
stoptime (num time)
Sets the time when the simulation should stop
Description
This command sets the time at which the simulation should stop running. The model will not necessarily stop at the exact time specified, but will stop at the first system check on or after the specified stop time. The model may stop early if there are no more events to execute. If time is -1, the command returns the current stoptime.
Example
if (stoptime(-1) < 500)
stoptime(500);

 This sets the stoptime to 500 if it was less than 500 to begin with.
store ()
Description
This command is deprecated. This command is currently deprecated because a faster leaner implementation of the undo functionality has been developed that does not use this command.

 It explicitly stores an archived copy of the current model inside the undo folder of the main tree. Refer to undos() command documentation for more information.
Example
store();
strascii (num asciivalue)
Description
This command returns a string that contains the character whose ascii value is character.
Example
strascii(91) + "alert(" + strascii(34) + "Hello There" + strascii(34) + ")" + strascii(93);

 This returns a string that contains the following phrase: [alert("Hello There")]
stringcompare (str text1, str text2)
Compare strings for alphabetical order
Description
Compare strings for alphabetical order. The return value is zero if the strings are the same. If text1 is alphabetically before text2, a negative number is returned. If text1 is alphabetically after text2, a positive number is returned. Same as the strcmp() C++ function.
Example
stringcompare("zenith","beta") returns 1

 comparetext("aqua","yellow") returns -1
stringcopy (str string, num start, num length)
Deprecated, use string.substr()
Description
This command is deprecated. Use string.substr() instead.

 Returns a substring of string defined by index start (base 1) and length.
Example
stringlen (str string)
Deprecated, use string.length
Description
This command is deprecated. Use string.length instead.

 Gets the length of string.
Example
stringpart (str string, num start, num length)
Deprecated, use string.substr()
Description
This command is deprecated. Use string.substr() instead.

 This command will return a portion of a string. The new string is defined with a starting character number and a length. A start value of 0 refers to the first character in the original string.
Example
stringpart("Hello",2,3) returns the sub string "llo".
stringreplace (str stringtosearch, str searchfor, str replacewith)
Deprecated, use string.replace()
Description
This command is deprecated. Use string.replace() instead.

 Returns a copy of stringtosearch with all occurrences of searchfor replaced with replacewith.
Example
stringreturn (str returnstring, ptr callpoint)
Description
This command is deprecated. You can simply return strings from C++ user commands with the return statement.

Prior to FlexSim 7.7, this command was used to return a string from a C++ implementation of a user command. This command was only needed in C++. In FlexScript user commands, you can simply return the string with the return statement.
Example
C++: stringreturn(result, callpoint); return 0;
stringsearch (str stringtosearch, str searchfor, int startindex[, int flags])
Deprecated, use string.search()
Description
This command is deprecated. Use string.search() instead.

 Searches the string for the given substring searchfor (base 0).
Example
stringtoken (str token, str delimit)
Finds the next token in a string
Description
Finds the next token in a string. The first parameter is a string containing delimited tokens. The second parameter is a string with a set of delimiter characters. Works similarly to strtok() in C++.
Example
string token = "Jacob,Emma,Michael,Isabella,Ethan";
string name = stringtoken(token,",");

 while(stringlen(name)>0)
{
    pt(name);pr();
    name = stringtoken(NULL,",");
}

This prints each name in the list to a different line of the output console.
stringtonum (str string)
Deprecated, use string.toNum()
Description
This command is deprecated. Use string.toNum() instead.

 Converts string to a num.
Example
stringtopchar (str string)
Deprecated, use apchar()
Description
This command is deprecated. Use apchar() instead.

 This command returns the string as a pointer to a C++ character. This is used to convert variables of type string to type char* for some C++ commands which only take char*'s. It is not needed in Flexscript.
Example
setname(current,stringtopchar("ThisObjectName"));

 This sets the name of the object referenced by current to "ThisObjectName". The stringtopchar() command may not be mandatory here, but it is legal.
strquote (str string)
Deprecated, use \"
Description
This command is deprecated. Use \" instead to include quotation marks within a string.
Example
strquote("hello")
sub (num value1, num value2)
Deprecated, use the - operator
Description
This command is deprecated. Use the - operator instead.

 operator instead. of value1 and value2. This returns the result of the arithmetic expression value1-value2.
Example
double operator instead. = sub(10,4);
suspenddraw (num bitmask)
Description
For developer use. Bit mask. Disables draw in window types. Bits: 0 - TREE; 1 - PLANAR; 2 - SPATIAL
Example
suspenddraw(1)
sv ()
Gets a reference to the last view desginated as sv()
Description
This command returns a reference to the last view window that was designated the selected view. To designate a view window, right-click on the window, not on any objects drawn in that window, and select "Set as (sv)". Any open view window (e.g. Ortho or VR) can be designated the selected view.
Example
flypath(sv(),1);

 This begins flypath number 1 in the view that is currently designated the selected view.
swapnoderanks (obj/node parentnode, num index1, num index2)
Swap the ranks for two nodes in a parent node's sub-tree
Description
This command swaps the ranks of two nodes in the parent node's sub-tree. Swapping ranks can be faster than using setrank() especially for very large lists of nodes.
Example
swapnoderanks(parentNode,4,parentNode.subnodes.length);

 This swaps the 4th ranked node in parentNode's sub-tree with the last node in parentNode's sub-tree. This can make removing that node from parentNode's sub-tree faster if the list is very long. Note that this will put the last node into the 4th position, so ordering in the tree should not matter to be able to do this. In other words, this would break fifo ordering.
swaptablecols (str/num/node table, num column, num column2)
Deprecated, use Table.swapCols()
Description
This command is deprecated. Use Table.swapCols(). instead.

 Swaps two columns in a table.
Example
swaptablerows (str/num/node table, num row, num row2)
Deprecated, use Table.swapRows()
Description
This command is deprecated. Use Table.swapRows(). instead.

 Swaps two rows in a table.
Example
switch (num value)
Description

Example
switch_statelocked(so(),1)
switch_stateused (obj thenode[, num off/on])
Description
For developer use. Get or set where a node inside a state profile is used by the object. This flag is automatically set in the setstate() command, so developers can know which states are used by an object, for UI development.
Example
switch_stateused(so(),1)
switch_variable (obj object, str var[, num off/on])
Description
For developer use. Add and set; or remove a dynamic switch variable to/from an object.

Description
This command gives you access to various information on a traffic control, as well as lets you direct the traffic control to perform logic. Logic/data that is performed/returned is based on the info parameter, as follows:

trafficcontrolinfo(tc, TCI_NR_ACTIVE_TRAVELERS) - returns the total number of active travelers in the traffic control.

trafficcontrolinfo(tc, TCI_ACTIVE_TRAVELER, num travelnr) - returns a reference to the nth active traveler in the traffic control.

trafficcontrolinfo(tc, TCI_ACTIVE_TRAVELER_COUPLING, num travelernr) - returns a reference to a coupling node, stored in the Traffic Control's variables tree, that is associated with the nth active traveler. This coupling can be used to stored custom user information regarding that active traveler. To do this, add sub-nodes to the coupling node with nodeinsertinto(), add data, etc. Note that once the active traveler leaves the traffic control area, the coupling, and its sub-nodes, will automatically be destroyed.

trafficcontrolinfo(tc, TCI_ACTIVE_TRAVELER_RANK_FROM_TRAVELER, obj traveler) - This command takes a reference to a traveler object and returns which index in the traffic control's active travelers is associated with that traveler. If zero is returned then the object is not an active traveler in the traffic control.

trafficcontrolinfo(tc, TCI_NR_MEMBERS) - Returns the total number of network nodes that are members of the traffic control area

trafficcontrolinfo(tc, TCI_MEMBER, num membernr) - Returns a reference the nth network node member of the traffic control

trafficcontrolinfo(tc, TCI_MEMBER_COUPLING, num membernr) - Returns a reference to a coupling node, stored in the traffic control's variables, that is associated with the nth network node member of the traffic control. Like TCI_ACTIVE_TRAVELER_COUPLING, this node may be used to store data associated with that network node.

trafficcontrolinfo(tc, TCI_MEMBER_RANK_FROM_NETWORK_NODE, obj netnode) - Takes a network node reference and returns the member index of that network node in the traffic control. If zero is returned then the network node is not a member of the traffic control.

trafficcontrolinfo(tc, TCI_NR_ENTRY_REQUESTS) - Returns the number of entry requests currently in queue waiting to enter the traffic control area.

trafficcontrolinfo(tc, TCI_ENTRY_REQUEST_TRAVELER, num requestnr) - Returns a reference to the traveler associated with the nth entry request, who is waiting get into the traffic control area.

trafficcontrolinfo(tc, TCI_ENTRY_REQUEST_NETWORK_NODE, num requestnr) - Returns a reference to the network node where the traveler is waiting, associated with the nth entry request

trafficcontrolinfo(tc, TCI_ENTRY_REQUEST_NODE, num requestnr) - Returns a reference to a node associated with the nth entry request. Like TCI_ACTIVE_TRAVELER_COUPLING, you may add sub-nodes to store data associated with the request. Do not, however, change the data on this node, as this is used by the traffic control logic.
trafficcontrolinfo(tc, TCI_ALLOW_ENTRY, num requestnr) - Calling this command will instruct the traffic control to allow the traveler associated with the nth entry request to enter the traffic control area.

trafficcontrolinfo(tc, TCI_SET_ENTRY_REQUEST_RANK, num requestnr, num settorank) - Calling this command will cause the traffic control to rerank its nth entry request to the specified rank.

 Also, a note regarding using the traffic control triggers to override the traffic control's default logic. The traffic control's OnEntryRequest trigger, which fires when a traveler first requests entry into the traffic control area, can take 3 different return values:

TC_ON_ENTRY_REQUEST_DEFAULT - If this value is returned from the trigger, the traffic control will perform its normal filtering logic.

TC_ON_ENTRY_REQUEST_ALLOW - If this value is returned, the traffic control will ignore its default logic and simply allow the traveler into the area. Note that if this is used, the traffic control will ignore its maximum capacity variable, so depending on the logic you define, the number of travelers in the area may exceed the maximum capacity variable you specify on the traffic control.

TC_ON_ENTRY_REQUEST_QUEUE - If this value is returned, the traffic control will ignore its default logic and add the request to its request queue, disallowing the traveler from entering the area at that time.
The traffic control's OnExit trigger may take one of two return values:

 0 - If this value is returned, the traffic control will perform its default logic, allow other travelers to enter, etc.

 1 - If this value is returned, the traffic control will do nothing. In this case the user should use the trigger to explicitly tell the traffic control which traveler(s) to receive using TCI_ALLOW_ENTRY.

 If you plan on implementing your own custom logic for allowing travelers into the area, then it is recommended that you use the traffic control's default "Mutual Exclusion" mode.
Example
treenode netnode = trafficcontrolinfo(tc, TCI_MEMBER, 2);
transfernode (node movenode, node container)
Deprecated, use treenode.up
Description
This command is deprecated. Use treenode.up to set the node's parent (container).

 This command moves movenode into the container node. This is like the moveobject command, except no events (ie. OnSend, OnReceive) are executed.
Example
transfernode(current.labels["inactivequeue"].first, current.labels["activequeue"]);
transfernodeobj (node movenode, node container)
Moves movenode into the container node's object data
Description
This command moves movenode into the container node's object data. This is like the moveobject command, except no events (ie. OnSend, OnReceive) are executed.
Example

transportincomplete (obj object, obj item [, num inport, obj transporter])
Notifies the FixedResource object that item will now be moved into it
Description
This command notifies a downstream FixedResource object that the specified item will now be moved into it from an upstream object. This should only be used if the upstream object's Use Transport field is checked, but you are moving the item explicitly, instead of using an FRLOAD task. This allows the downstream FixedResource to manage data on how many items are slated to enter the object, but haven't arrived yet. Execute this command just before you move the item out with the moveobject command. For more information, refer to the FixedResource documentation. If this command returns 0, then the object has been stopped using the stopobject command, and you must wait until it has been resumed before moving the item into it.
Example
transportincomplete(current.outObjects[port], item, opipno(current, port));

This example should be executed from the Request Transport From field before a moveobject command if you decide that you don't want to use a transport, but rather want to immediately move the flowitem
transportoutcomplete (obj object, obj item [, num outport, obj transporter])
Notifies the FixedResource object that item will now be moved out of it
Description
This command notifies the FixedResource object that the specified item will now be moved out of it. This should only be used if the object's Use Transport field is checked, but you are moving the item explicitly, instead of using an FRLOAD task. This allows the FixedResource to manage data on how many items are still in the object but are ready to leave. Execute this command just before you move the item out with the moveobject command. For more information, refer to the FixedResource documentation. If this command returns 0, then the object has been stopped using the stopobject command, and you must wait until it has been resumed before moving the item into it.
Example
transportoutcomplete(current, item, port);

 This example should be executed from the Request Transport From field before a moveobject command if you decide that you don't want to use a transport, but rather want to immediately move the flowitem
travelto (obj object, obj spline, num x, num y, num z, num vmax, num acc, num dec)

Example
travelto(traveler,NULL,100,100,0,5,1,6)
traveltoupdate (obj object [, obj spline])
Deprecated, use kinematics
Description
This command is deprecated. Use kinematics instead.

undos (num off/on)
Description
This command is deprecated. This command is currently deprecated because a faster leaner implementation of the undo functionality has been developed that does not use this command.

 This command is used to turn on (1) and off (0) the automatic saving of model copies each time there is a mouse click or key press. Use the setundos command, to specify the maximum number of model copies that will be remembered for undoing. To function correctly, this command requires first creating a node in the main tree named undo and giving it number data.
Example
undos(1);
uniform (num min, num max[, num stream])
Returns a random number between the min and max values
Description
uniform( a, b, stream ) is a bounded continuous probability distribution.

b defines the maximum variate
b−a is the scale parameter
stream is a reference to one of FlexSim's random number streams {0,1,2,...}

Outputs:
range = [ a, b ]
mean = ( a + b ) ⁄ 2
variance = ( b−a )²⁄ 12

Used to approximate a value that is felt to be randomly varying between a and b but hardly anything else is known.

Comments:
There is an equal probability that an a, or b, or any real number inbetween will be returned.
The uniform(0, 1) distribution is essential in generating random variates from all the other distributions and will return a continuous set of random values between and inclusive of 0 and 1.
Example
uniform(12.3, 27.5, 3);

 Random number stream 3 will be used to generate a random variate from a uniform distribution having a minimum of 12.3 and a maximum of 27.5.

γ is the location parameter ∈ ( - ∞, ∞ )
β is the scale parameter ( β > 0 )
α is the shape parameter ( α > 0 )
stream is a reference to one of FlexSim's random number streams {0,1,2,...}

Outputs:
range = ( γ , ∞ )
mean = γ + ( β⁄α ) Γ(1 ⁄α) where Γ() is the Gamma function.
variance = ( β²⁄α ) { 2Γ(2 ⁄α) − 1 ⁄α [ Γ(1 ⁄α) ] ² }

Probability Density Functions:



Possible Applications:
The weibull distribution is commonly used when there is not sufficient data available because it can take on so many different shapes depending on the shape factor. It is a very common distribution used for representing the time between equipment failures, as well as the time to complete a manual task.

Comments:
The weibull( γ, β, 1 ) and exponential( γ, β ) distributions are the same.
The weibull( γ, β, 2 ) and rayleigh( γ, β ) distributions are the same.
The weibull distribution is skewed to the left if α > 3.6
Example
weibull(0, 2, 3, 5);

A weibull distribution with a location parameter of 0, a scale parameter of 2, a shape parameter of 3, and random stream number 5.
