Returning information back from an external program called by Smart Assy

[ptc-198847]

Is it possible to return values back to the SA Application after calling an external program/method?
With the PLUGIN command, I know you can pass arguments to an external program

I'm guessing that you can't do that directly, but you could probably have the program you are calling via PLUGIN store data in a text file or perhaps a spreadsheet and then read that data back into SmartAssembly.

Design well!
