RE: Cvt RPG III to RPG IV (strange problems )

Frank,

I don't think you were bitten as much by converting from RPG to RPGIV, but by 
getting out of the OPM Activation group scheme.

The OPM Activation group scheme seems to be that programs all run in the 
*Default activation group.  Everything is in the same activation group, and you 
don't do a RCLRSC.  If you compile everything to run in the *Default activation 
group most activation group problems you mentioned would go away.

The application was originally written in OPM, and runs that way.  Now, if you 
want to further get away from the OPM model and run in different activation 
groups, it is time to hit the ILE Concepts, as others suggested, and determine 
which would be the best method for your application.  There are different 
schemes you can go with, depending on what works for you.

Some people run different activation groups depending on application, an AP 
activation group, an AR activation group, Invoice, etc...

What seems to be a fairly common practice, from messages I see, is to have an 
initial program either run in a named activation group, or *New, and sub 
programs run in *Caller.  Again, what works best for you.

Regards,

Jim Langston

I have finally bitten the bullet and converted all our RPGs to RPGIV.
Occasionally I see questions asked about the reason to convert and
see the standard reply's about better functions, modular code
more modern techniques etc. I wonder what others have experienced.
This is a brief list of GOTCHAs i got.
