hi Simon,
My confusion stems from the fact that if C is instructed to not widen
then why does RPG need *CNOWIDEN when that's RPG's default behaviour?
What is RPG doing that requires it to be *instructed* to behave
differently?
There's a difference specifically in the way 1-byte return values are
passed. When ILE was implemented, C and CL passed them one way, and RPG
and Cobol chose to pass them differently. (I think C and CL pass them
as an integer, and RPG and Cobol pass them as character strings... and
there's some sort of a difference in the mechanism somewhere deep under
the covers.)
Unfortunately, I don't know exactly what that difference is.
however, I believe *CNOWIDEN tells RPG to use the same convention that C
(and CL) use for 1 character return values.
