You are probably right about that. I will start one and see what they reply.

A similar issue happened with BPXWDYN. COBOL can't set R0. So a new entry point in BPXWDYN was created that handled that problem. This all started with me writing an RCF to tell them that they didn't have a COBOL example. Then a C programmer (I'm guessing) wrote the COBOL code. You can write c in any language (one of those type of things). Problem is, it would confuse most COBOL programmers that, well, it would confuse most COBOL programmers, and so I suggested a few changes to solve the issue. Then one of their own people onfirmed what I said, it would be confusing to most COBOL programmers. And so it appears that IBM doesn't have many product developers that actually know COBOL..... That has been my take-away from that exchange. So you may need to do an RCF, and you may go a few rounds with them. Just say'n'.
