Description

This function adds a new global script variable to the document.  If the value of the newly added variable is desired to be changed during the same script execution in which it was added, the SetGlobalVarValue command must be used.

 

Syntax

id = AddGlobalVar( varName, varVal, varComment )

 

 

Parameters

id (Long)

ID number of the newly added global script variable.

 

varName As String

Name of the global script variable being added.

 

varVal As Variant

Value of the global script variable being added.

 

varComment As String

Descriptive comment for the global script variable being added.

 

 

Example

The following example checks to see if a specific variable exists in the document and it is either added or retrieved from the document depending on the check.  The variable value is then modified and set back to the variable.

 

          Dim ii As Long

          Dim varVal As Double

          Dim varName As String, varComment As String

 

          ClearOutputWindow

 

          varVal = 5

          varName = "g_myGlobalVar"

          varComment = "Variable added from a script."

 

          'check if the variable already exists and either add or retrieve it

          ii = FindGlobalVar( varName )

          If ii < 0 Then

                    ii = AddGlobalVar( varName, varVal, varComment )

                    Print "Initial variable value is " & varVal & "."

          Else

                    varVal = GetGlobalVarValue( ii )

                    Print "Initial variable value is " & varVal & "."

          End If

 

          'now modify and set the variable value

          varVal = varVal + 10

          SetGlobalVarValue ii, varVal

          Print "Modified variable value is " & varVal & "."
