At it's most basic...

The cycle is an implicit DOU %eof(Primary) loop.

There's lots more too it, but that's the key.

Need a program to print a list all customer names in the CUSTMAST file?

Create an RPG program with
 - declare CUSTMAST designated as a primary file. (f-spec)
 - declare a printer file (f-spec)
 - define output record for the printer file (o-spec)

And boom, you're done.  Not a single line of executable code (c-spec)
written by you needed.  The cycle handles input and output.

(Ok, I'm ignoring printer overflow handling, but even that's handled in the
o-specs IIRC)
