Identify Primary Script from Sub Script

[Courtney]

Is there a GET function or other method to retrieve whether another script is running or which scripts are running from inside a script?

I have a script that will call a sub script, but I also use the sub script as a stand-alone in some cases, so I'd like to be able to check from within that script whether it was called by another script, so that I know how to handle things when the sub script ends (either go back to the main script with the Exit Script step or go back to original layout and Halt Script.)

I figure I can use a variable to do this, but I'm wondering if I'm overlooking a cleaner way.

Have the main script call the sub-script with a parameter?
