I'm very confused by this scenario.  Where exactly is the CLP (OPM CL?!) 
being called?  You say that the RPG program is calling ITSELF 
recursively, that would imply that it's never calling the CLP, right, 
since it's calling itself?

Also, since each new call to the RPG is generating a new activation 
group, you need to tell us how you handled the override scoping. What do 
you have for the OVRSCOPE parameter on OVRDBF?

Also, remember that in a call-stack model, higher-level overrides take 
precedence over lower-level overrides.  If you're using call-stack 
scoping, that means that only the first override matters, and the 
recursive ones will have no effect unless they specify SECURE(*YES).

You're doing a lot of things that I would never do:

a) Recursive calling of a program (as opposed to a procedure) is 
something I'd never do.  The performance is awful, the stack is limited, 
and there's really no reason to do it.

b) Using CALL/PLIST instead of a prototype.

c) Also, there are good and bad reasons to use OVRDBF.  I have to wonder 
why you're using it?
