====== Set Pipeline Parameter From For Loop ======
The **Set Pipeline Parameter From For Loop** command can be used to create a new pipeline parameter that is used to mimic a traditional for loop. 

Traditional for loops are numerical representations, such as:

For i=1 to 10 step1
Visual3D's For_Each loop are string entries that are specified explicitly by the user.

This command creates a string expression.

====Pipeline Command====
The command can be found in the Pipeline Workshop within the Pipeline Control folder as so:
<code>
Set_Pipeline_Parameter_From_For_Loop
/PARAMETER_NAME=
! /PARAMETER_INDEX_START=
! /PARAMETER_INDEX_END=
! /PARAMETER_INDEX_STEP=
! /PARAMETER_INDEX_TYPE=INTEGER
;
</code>

====Command Parameters====
The following table shows the command parameters that can be used to define the command and their descriptions:

|**Parameter**   |**Description**|
|**Parameter Name**|Name of the parameter to be set|
|**Parameter Index Start**|Starting value of the index|
|**Parameter Index End**|Ending value of the index|
|**Parameter Index Step**|Size of the step between index values|
|**Parameter Index Type**|Type of output value (I.e. float, integer)|


====Example: Integer loop ====
This example shows how the command can be used to generate an integer loop:
<code>
Set_Pipeline_Parameter_From_For_Loop
/PARAMETER_NAME=INT_VALUES
/PARAMETER_INDEX_START=1
/PARAMETER_INDEX_END=10
/PARAMETER_INDEX_STEP=1
/PARAMETER_INDEX_TYPE=INTEGER
;
</code>

on execution the results are

INT_VALUES = 1+2+3+4+5+6+7+8+9+10



====Example: Float loop ====
The following code shows how the command can be used to create a float loop:
<code>
Set_Pipeline_Parameter_From_For_Loop
/PARAMETER_NAME=FLOAT_VALUES
/PARAMETER_INDEX_START=0
/PARAMETER_INDEX_END=5
/PARAMETER_INDEX_STEP=0.5
/PARAMETER_INDEX_TYPE=FLOAT
;
</code>

FLOAT_VALUES = 0.000000+0.500000+1.000000+1.500000+2.000000+2.500000+3.000000+3.500000+4.000000+4.500000+5.000000

====Example: Defining Command with Expressions ====

The start, end and step parameters will accept expressions.

Create 3 global metric signals:

<code>
Metric_Explicit
/RESULT_METRIC_NAME=GLOBAL::START
/RESULT_METRIC_FOLDER=COUNTER
/METRIC_VALUE=0
;

Metric_Explicit
/RESULT_METRIC_NAME=GLOBAL::END
RESULT_METRIC_FOLDER=COUNTER
/METRIC_VALUE=5
;

Metric_Explicit
/RESULT_METRIC_NAME=GLOBAL::STEP
/RESULT_METRIC_FOLDER=COUNTER
/METRIC_VALUE=1
;

Set_Pipeline_Parameter_From_For_Loop
/PARAMETER_NAME=FLOAT_VALS
/PARAMETER_INDEX_START=GLOBAL::METRIC::COUNTER::START
/PARAMETER_INDEX_END=GLOBAL::METRIC::COUNTER::END
/PARAMETER_INDEX_STEP=GLOBAL::METRIC::COUNTER::STEP
/PARAMETER_INDEX_TYPE=FLOAT
;
</code>

FLOAT_VALS = 0.000000+1.000000+2.000000+3.000000+4.000000+5.000000
