I have a prg that receives parameters and returns a value. It does not have "Procedure" line at the top, it's just code in a prg.

The last line of the file returns a value with RETURN lnReturn

So, how do you call a PRG in a way that you can capture the return value?

I've tried stuff like:

Do Blah.prg with 'SomeString' to lnReturn

and other goofy attempts, but none have worked.

What to do?
