SetVariableValueInt32

SetVariableValueInt32Method

Sets the value of a 32-bit integer variable

Syntax

SetVariableValueInt32(Value)

Parameters

Value

Int32

32-bit integer value that the variable will be set to

Returns

Nothing

Remarks

This lets you set the value of a 32-bit integer variable defined with DefineVariable (or Define) . This works for both signed and unsigned 32-bit integers.
