Re: MI embedded in RPG (ZMILIB/CRTRPGMI?)

GENOPT(*LIST) is kinda fun - I learnt about it when I was first introduced to System/38 back in CPF v5 timeframe. I was doing COBOL at the time - and if anything the commenting in the generated COBOL code is even better than for RPG.

We used to use the MI listing to help us work around the bugs in the COBOL compiler that we encountered while doing an NCR -> S/38 conversion. Later when I joined IBM in 1986 the compiler team were amazed at the number of bugs I reported within the first few months I worked there. We’d been working round them for years but we never had the time to go through the reporting process!

Pity something similar wasn’t doable with the ILE compilers - but that’s another story.

First of all, thanks to everyone who responded.

Jon, I had never thought to explore GENOPT(*LIST), and now that I
have, I must say I'm pretty impressed. The generated MI code even has
comments! As for the C-wrapper approach, once you mentioned it, I
started doing some more Googling and found this, which you may find
familiar:

Yeah, it's 10 years old, but that still makes it several years newer
than the program I'm dealing with.

I have follow-up comments for some of the other respondents as well,
but right now I've got to run.
