Modular design

["Tom Tufankjian" <Tom_Tufankjian@xxxxxxxxx>]

I'm just getting my feet wet with RPGLE and I have a design question.   I
have 3 workstation programs, pgma, pgmb, pgmc.  Each one processes one
screen of a display file.  Pgma is a subfile program where the user can
drill down and it calls pgmb.  Pgmb is a subfile program also where the
user can drill down and call pgmc.  Pgmc is not a subfile program.

Right now I have pgma as a regular rpg400 program doing a regular non-bound
call the pgmb.  Pgmb and pgmc are bound
together and pgmb does a function call to a procedure in pgmc.  All the
programs are in activation group QILE.

Also, I am calling pgma from a cl program which does a rclactgrp QILE after
the call to pgma so that all the files are closed.  Can't I do this from
the rpg program pgma?

Is there a better way to group the modules?
