Re: OT: Re: How to work with Arrays using positional RPG IV

Big smile Jon, I loved it :) You always knew exactly what was happening
(well, except for the IO macros which could always have a problem that you
couldn't (easily) see). Remember that I did point out that assembler was
my favorite language but decidedly not my most productive. I will
(generally) take RPG whenever appropriate. The one language I really can't
stand, and it's just heritage I think, is C. If I add 1 to a pointer I am
anticipating addressing the next byte of storage, not the first byte of the
data type the pointer is associated with. It's those little things about C
that drive me crazy (and also caused some real learning experiences for
PL/MI developers back in the lab -- some of which came to me when they
couldn't figure out what in the world their C program was doing). Every
language is good, but some take a definite shift in thinking (and I prefer
lazy thinking in terms of storage addressing lol)

I spent 6 weeks trying to find a big in the S/34 COBOL compiler ... turns
out it was mostly due to an idiot programmer whose twiddling of bits in an
instruction didn't actually do what his comments said! It did the
opposite. But as you know the debugging was primitive to put it mildly.
Takes a long time to debug when stepping one instruction at a time!

And no - i don't remember it fondly!

Jon,

Oh no, PL/MI is nothing like assembler (which I'm well aware you know).
I'm talking 370 and (does anyone remember it?) the S/34. Oh those were
the
days, microfiche for the operating system and away you go :)

"Assembler" as in PL/MI Bruce ? I suspect that even MI would be too high
level if you really want to bit twiddle!

Interestingly had the original question been about C or MI I could
understand it since they still have utility. It was ancient RPG that
got me
and (at the time) I didn't know we were talking V5R4.

I agree. In a similar vein, my favorite language is assembler though
assembler is NOT at the top of my productivity languages. But it is so
fun
:)

Each to his own perversion I guess.

Exactly.

Messing with a Commodore is fun though (albeit slow fun) but fixed
from
RPG?

Where's the fun in cumbersome PEEK and POKE because of the limitations
of
the ROM-Basic? How can it be fun to put your programs on really slow
audio
cassettes, with the need to manual adjust volume for omitting
distortion?
Where's the joy about sitting in front of an old, blurry and 60 Hz
refresh
TV giving you a headache from flickering? How can even typing on that
dreaded keyboard even be fun?

Maybe this helps you understand. ;-)

Sorry the joy completely escapes me - it is not as if the world needs
any more examples - there are enough of them out there.

I guess because you're doing IBM i for a living, and you've gone
through
all the modernization features you learned to love, I assert you have
a
different, professional view on the topic. :-)

My first real AS/400 experience started not much more than a decade
ago,
from zero, with a model 400 with a license V4R4 and erased disks. Even
my
solid background on Linux and Networking wasn't of much help. I'm not
doing
all of that for a living, but because I can, because I want and
because
I
feel a great appeal to the way the (older) machines are engineered.
