Description 
If a variable doesn’t exist, this script step will create one. A variable name has the same naming restrictions as a field name. For more information, see About naming fields.
Local and global variables can be created and used in calculations.
 •
A local variable can only be used in script steps in the currently executing script. The value in a local variable is cleared when the script exits.
 •
A global variable can be used in a calculation or script anywhere in a file, for example, other scripts or file paths. The value of a global variable is not cleared until the file is closed.
 •
Local and global variables (or even two local variables in different scripts) can have the same name but they are treated as different variables and can store different values.
Examples 
The following example sets a local variable.
Set Variable [$commission; Value:.05]
The following example sets a global variable.
Set Variable [$$commission; Value:.1]
The following example sets a global variable at a specified repetition number.
Set Variable [$$bonus[2]; Value:3 * 4]
