RE: RPG III to RPG IV

It's a toss up on speed.  I've seen both arguments that say each is faster.

As for size, RPG/IV objects may be a little bigger.  CLLE objects will be
larger than their CLP counterparts.

As for memory, most likely RPG/IV will need more.  Not for sure...

But....

Maintenance will be so much easier as your code can be changed to be free
format.  If you plan on simply running the CVTRPGSRC command on all your
programs and recompiling, I would wait until your software needs a rewrite
to convert from RPG/III to RPG/IV.  This way you can really make your code
much more readable.

Also, I have a tool that you can run after the CVTRPGSRC command to change
your source to free-format expressions.  It is a step towards rewriting, and
makes the code more readable.  (Well, to most...)

follow the download link and download the CVTILEFMT (Convert ILE Format)
tool and try it out on a couple of your programs.
