If either RPG+COBOL or CL had changed how they handle 1 byte character/indicator return values, it would have required a recompile of all existing programs.

I've felt that CL could be more flexible than that. We've seen plenty of new commands and command parameters over the years, not to mention new data types. I wouldn't have been at all surprised to see a new parm added to CALLPRC that simply returned the value differently.

Or a new RtnVarAs() parm that defaulted to *PREVIOUS behavior, but allowed a new value of *RPGV6R1 (or whatever) to described _how_ a value should be returned. Developers could choose how/when to convert existing code.

Anyway, it seems to me that many possibilities could have handled a transition with minimal need for recompilation. Or is the ILE CL compiler too different from OPM to allow it?
