RE: Benefits of Sub-procedures

["DeLong, Eric" <EDeLong@xxxxxxxxxxxxxxx>]

JT, in part the discussions bounce back and forth between "simple" and
"complex", and the examples seldom cover both.  Originally, the question was
"how to begin", then quickly became "why even try".....  

I never saw "module should have one procedure" as a goal.  That's but one
possible way of approaching this.  I myself advocate grouping of similar
procedures into a single source member / module, which would then usually
become its own service program.  I don't like module objects lying around,
so I prefer the CRTBND* commands and binding directories to help the
compiler find my procedures.  

Like everything else we do, we must learn and understand the implications of
our design choices.  It is easy to get into trouble when we use technology
we don't understand.

Bob, I agree to an extent.  I don't like the colon, nor free-form.

But the bright people got it wrong on how to deal with adding one to a
transaction number, afaik.  I look at the views, by many VERY bright people,
that a module should have one procedure, and I sure think/believe they've
got that wrong...  (Don't agree that's the stupidest thing I've ever seen,
when compared to interfacing with an API using XML, for example!)  There is
a fair bit of confusion about "best" practices in procedures, from THE most
experienced and (imo) brightest people.

How is that??

And I can assure you that EVERY programmer on the face of the earth can and
has gotten into some trouble when they "assume things work they way they
think they should <when> that is often <not> the case", and that's not
language-dependent.  I would be of the opinion, that as RPG gets (imho)
less-intuitive, that's gonna happen more than less.
