Re: Maintaining old RPG 2 or 3 code on RDi

I remember CVTRPGSRC just leaving things that did not convert in a C spec line. It never failed. A lot of /FREE, /END-FREE Back when we converted.

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

convert,

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.
