Re: Help us migrate to ILE RPG

[<groyle@xxxxxxxx> (Gordon S. Royle)]

Hi Joep

You mentioned OVRDBF in an OPM CL program being a problem. Is OVRPRTF a 
potential problem too? We are experiencing intermittent problems with 
OVRPRTF. Sometimes it works, sometimes not.

Buck,

This is not true, there is ILE here.  As soon as you compile with
DFTACTGRP(*NO) you are creating a 'real' ILE program.  If you want to use
RPG IV in an OPM environment, you'd better stick to DFTACTGRP(*YES).  Sadly,
this means no subprocedures.  Of course there is nothing wrong with building
real ILE programs, but mixing those with OPM programs can be tricky (e.g.
OVRDBF + OPNQRYF in OPM CL, then calling an ILE RPG program ...).
