RE: RPG/COBOL/C

On an iSeries why would any one compiler generate different code than another?
Unless the compiler is a living organism,
I would expect one to be a byte for byte copy of another within the same OS
version and level.

It's hard to imagine how that could be true. I can imagine a particular
RPG compiler generating worse code than a particular COBOL compiler, but
I can't imagine how all RPG compilers would generate worse code than
all COBOL compilers.
