Good morning all,

This is perhaps a bit of a heavy topic for a Monday morning, but it's 

on

my mind so I'll ask.  Does anyone have any references or sample code 

which

gives some guidance on structural programming techniques for separating
display logic from business logic in RPG.  I am familiar with the
Model-View-Controller (MVC) technique in OO languages, but I am having
trouble figuring out the best way to apply these sorts of techniques in 

a

structured programming environment.

Any guidance would be much appreciated,
Adam

I have some notes from a project where we separated business logic
from presentation logic.

http://www.pando.org/downloads/alsp.doc
http://www.pando.org/downlaods/alspmods.doc

alsp stands for Application Logic Service Program.

All V3R2 (sorry, an old project).

The first doc lists all the procedures we found necessary
to implement an interface much like PDM's.

The second doc lists (on a very high level) modifications
required to an interactive template program in order
to utilize the ALSP.

I have source code as well, but since I've been known
to prefix my variables with an '@' sign, I won't post links
here :)

It's not much, but sometimes just knowing what
procedures need to be written is a help,

Chris
