Re: Procedures/SubProcedures

[Paul Tuohy <tuohyp@xxxxxxxxxxxxx>]

Hi Ron,

OK. Yes, we use the two terms interchangeably but if we were being pedantic,
there is a difference (at least as I understand it).

A procedure would be the "mainline" of a program. When you issue a call to a
program, the entry point is the PEP (Program Entry Procedure) or the Mainline in
a specific module. If you use the CALLB operation to call another "module", you
are calling the mainline (or PEP) in that module.

Subprocedures are "sub" to the main procedure (PEP) in a module - if a PEP is
defined. i.e. there is a mainline and you have not specified NOMAIN on the H
Spec.

But since all procedures/subprocedures can be exported - the terms are really
interchangeable.
