Re: Maintaining old RPG 2 or 3 code on RDi

DEBUG - yea - well - let's just say that many better options had been added over the years. Personally I wanted to throw out GOTO too but I lost that battle!

As to Auto Report - we couldn't find anyone actually using it for real. In all the cases we studied it was simply being used to allow more than one spec type to be incorporated in a single /COPY member.

DEBUG is another...

DEBUG (Debug Function)
The DEBUG operation helps the programmer debug a program that is not working
properly. One or more records containing information helpful for finding
programming
errors are written as a result of this operation. You can use the DEBUG
operation
independently of or in combination with the OS/4ðð testing and debugging
functions


Lastly, RPG "auto report" programs , member type RPT or RPT38, compiled
with Create Auto Report RPG Program (CRTRPTPGM)...

Don't have a RPGIV equivalent.

There's at least one op-code in RPGIII

FREE (Deactivate a Program)
The FREE operation removes a program from the list of activated programs,
frees
static storage, and ensures program initialization (first cycle
processing) the next
time the program is called. It does not close files or unlock data areas.

That doesn't have an RPG IV version...thus CVTRPGSRC fails...

That's the only one I remember off the top of my head...

Unless you happen to be using one of the few op-codes that don't

there's little excuse not to convert. And if you do use one of those
non-converting op-codes...you're probably using it wrong anyway ;)

I was pretty certain that any valid RPG-III code would always convert to
compilable RPG-IV code using CVTRPGSRC. But, it's been so long since I've
had to deal with that, I'm not sure. I know that /free calcs obsoleted
some of the obscure opcodes, but a plain vanilla conversion using
CVTRPGSRC
should always convert to compilable code.
