Q: "What is The RPG Program Cycle, and what is it good for?"

A: It is an implicit "do-until-completed" loop, with implicit file I/O
available if needed, that is found in all RPG programs unless explicitly
disabled.

In addition to its original purpose of report generation, it provides
a simple way to implicitly perform a given operation on all records of a
file, or to set up a program to implicitly repeat any operation (such as
a user interaction) until a "work completed" condition is raised.


And I do hope the fellow(s) who "did not know sh** from Shinola" didn't
get a job as a shoeshine! (Or as a stablehand, for that matter!)
