Re: the cycle that never ends

I've always felt the The Cycle is an optimum way of structuring a
program: Read some data, do something to it, and put some of it
somewhere. IBM used to have a process known as HIPO: Hierarchy: Input,
Processing, Output. I don't know if it referred to The Cycle, but it seems
to fit!

I used to write COBOL programs structured like The Cycle. It kept things
organized!

Of course, lots of the reason for The Cycle was due to processing data on
Unit Record equipment (ie card readers), and being descended from
plug-wired processing equipment. Not having DO WHILE and DO UNTIL
constructs until relatively recently was another reason!

I love the RPG Cycle. It is fast, efficient, and simple to use when you
need to process everything in a file. I stopped using it for interactive
programs years ago but still have several audits that compare two files
across two systems, (DDM) and it works beautiful. However none of our
programmers here seem to be able to understand them. Sad when they all are
older than I and used the cycle before I.

I followed the posts on training new hires, and laughed to myself with
some of the comments only because many of those apply to me.
Today, a friend brought me an RPG book on training new hires, and it
states:
"Similarly, RPG still supports the "program cycle," although few RPG
programmers are old enough to remember how it works. "

Again, I laugh ... since I am one of the "few RPG programmers", but should
it not read..
"are wise enough to remember how it works:"

and should I be embarrassed to say, we still have some of those cycle
programs still running.... and with each upgrade, they still work :)
