Re: RPG III (RPG/400) -- WDSCI-L

Charles,

I thought this was odd too, but most of the core logic in XA is still RPG/400. I would not doubt it if some is still from the Mapics days. I do believe their newer stuff is RPG IV fixed. Their code generator for user exists can't handle field names over 8 characters in length. Their warning message says 6, but we have found we can push it to 8.

We run supported. That is the main reason we don't convert their stuff to RPGIV. It would further lengthen the apply ptf process. There have been several cases where if I am making a change to vendor's RPG/400 source and instead of doing it there, I add a 'simple' CALL and do my coding in a RPG IV program. In most cases it is not that easy because you have to make changes all over the place.

Thanks,
Scott Johnson

I don't quite understand this...

I'd expect any current version of a vendor package to be RPG IV at this point. If for no other reason than it saves having to require new customers to buy both OPM and ILE compilers. In fact, during our recent ERP search, both packages I looked at were RPG IV. Maybe not as much ILE as I would have liked, but they both were at least using RPG IV and some ILE.

If you're running unsupported, then I'd follow Buck's example of converting to RPG IV for any changed program.

Honestly, I've got some unsupported RPG III, and even if all I'm doing is looking at the source, I'll convert it to RPG IV (in a temp library) and pull it up in RDi.

We are using Infor XA. So for that we still see a lot of RPG/400. (A
couple of them have hit the 50 file limit.) Existing in-house programs
that have been developed in the past are a mix of RPG/400 & RPG IV
(both fixed and free).
New in-house is RPG IV Free.

We did get RDi 9.1.1.1 installed on all of the developers PCs recently.
They also went thru a training session with IBM. Those that have tried
RDi like it. They just tend to fall back to old habits.
I pretty much use RDi fulltime. It is funny because they will ask me
how to do something in greenscreen TurnOver and I can't remember how to do it.
But I can go into the RDi plugin and do it in no time flat without
even thinking. :)

I'm wondering how many people using RDi are still supporting RPG III
(RPG/400) code? All of our new development is done in RPG IV but our
manufacturing and financial systems are old purchased software
originally written in RPG III (RPG/400). There are some functions that
aren't supported for RPG member types and some that is not missing but
for all practical purposes is hidden unless you know the shortcuts.
I'm pretty sure we're in the minority but am wondering how many of us are out there.
