It's not complexity, it's hiding what the program is doing. I (and a
bunch of us) have written RPG for years and years, and I know the
cycle cold. I taught the cycle for years. And any graybeard RPG
programmer should know the cycle. But that's not the point IMO - it's
that others, especially new people, won't know it. Sure, they can
learn it...and they can have the opinion that RPG really is a Report
Program Generator with Specifications. Or, they can learn cycle-less,
free format, RPG/IV code, and use all the techniques that they learned
in school. I would rather have RPG be a mainstream language rather
than a specification language. I don't think the cycle makes a program
more efficient; it just removes lines of programming code that a lot
of people would expect.

Does anyone know if using the cycle makes a program more efficient,
less efficient, or it doesn't matter? Files still need to be opened,
records still need to be read...I dunno.

as if it is tough to understand. To my mind it essentially is a means
of doing the housekeeping for you. Just let the system open and close
files, read records, keep track of level breaks, and do the multi-file
processing. There's no need to create the same hamster wheel over and
over. Where is the complexity that scares everyone?
