RE: [Re: RPGILE V4.3 Gotcha] -- RPG400-L

Hans,

I could not agree you more.  Our company has been slow in moving to TRUE
RPGIV.  And even slower going to ILE.  We are way behind in our enhancement
list.  It has been extremely hard to find good RPG programmers in our area.
We are just starting to use the EVAL and I love it.  As with coding with the
old op codes one must take into consideration the intermediate results.  I
think the rules are clear and strait forward.  Yes I would love the
"infinite precision with infinite speed" but that is not a reality.
Hopefully IBM can put a faster arithmetic processor into the Power PC chip
and give you the means to increase the decimal precision beyond 30.  But
what would be enough?  I try to never use the "H" spec for performance
reasons and use the extender where I feel it is necessary.

But then 15,2 x 5,3 / 15,2 might be the biggest Eval I use.  The
intermediate would be a 20,4.

Great job Hans and Co,

I know I should just let this thread drop, but there are still some
interesting aspects to this discussion.

In my humble opinion, too many programmers are too
complacent about their craft.  It is all too easy these days to
pick up something new, have some early successes, and think you
know all about it.

Me, I started learning programming in 1976.  And I'm still learning
programming.  I didn't stop learning when I quit school in 1980.

Then I take it you haven't yet learned object-oriented programming.

Learning programming is much more than just learning the peculiarities
of particular programming languages.  Take OOP for instance.  In my
opinion, no-one schooled in procedural programming can really understand
object-oriented programming without first feeling like a complete
idiot.  If you think you know OOP without going through that phase, you
really don't know OOP.

The realization that one must pass through through that "complete
idiot" phase is hard for many people to accept.  We don't like
feeling like idiots.  Yet, IMHO, it's often necessary to shake off
old prejudices and beliefs in order to learn and accept new things.

(On the other hand, IMHO, over time, the teaching of OOP will improve to
make the process less painful.  But then again, the need to teach new
tricks to us old dogs will decrease as we retire and more and more new
programmers learn OOP right from the start.)

But here's what I don't understand with this discussion:  Learning a
new set of arithmetic rules in a programming language really doesn't
compare with learning a whole new way of approaching programming or
a whole new operating system.  Many RPG programmers have made the
transition to RPG IV with little effort and few complaints.

Look, I've stated before that, sure, we could have made some better
design choices.  But we have a policy of trying to ensure that a
working program compiled several years ago will work the same today
when compiled on a newer release.  We can't go back and arbitrarily
change the rules, and our customers expect that.

Cheers!  Hans
