I guess I hoped that the RPG compiler would recognize that a large return

It could do it under the covers if it was a non-exported procedure and it didn't check %PARMS.

But it couldn't do that if the procedure was exported since both caller and callee have to use the same mechanism. The large-return-value problem comes up most often with string-handling procedures, and those tend to be exported from service programs.
