RE: Recursive Calls

["Stone, Brad V (TC OASIS)" <bvstone@xxxxxxxxxxxxxx>]

In cases like this, where folks can go from one screen to another (only two
pgms), we add a parameter with the name of the calling program.  So if
they're in PGM A, go to PGM B, and then hit a key to go back to PGM A, we
check that parameter.  If it's PGM A, we simply "emulate" the user
cancelling out of the program.
