Converting to ILE

["Bruce Guetzkow" <bruceg@xxxxxxxxxxxxxxxxxxxxxxx>]

All:

I know I've seen this somewhere, but can't find it, no matter how I try.

I want to convert all current RPG-III source members to RPG-IV.  In
addition, I plan to convert all CLP to CLLE.  I know about CVTRPGSRC
(I've used it at another employer in the past, several years ago).  I
know that CLP = CLLE as far as the source is concerned, excepting things
like CALLPRC and other ILE-specific commands.

What I am looking for is a list of "issues" with converting.  It has
been some time since I did anything with converting, but I remember the
following:
- a couple RPG op-codes don't work or won't convert (FREE, at least one
other)
- OVRDBF OVRSCOPE parameter needs to be properly scrutinized (*CALLLVL,
*JOB, *ACTGRPDFN)
- RCLRSC behaves differently under ILE (i.e.:  avoid like the plague)

I feel comfortable dealing with the above issues (I don't think we have
any programs with FREE and most of the CLs with RCLRSC are batch anyway,
so they will be easy to change).  I just need to know what other issues
exist.

I don't plan to do more than use IBM's CVTRPGSRC command for now.  I
will be restructuring code over the next year or so and will rewrite
code as procedures and in free-format at that time.  I want to move to
RPG-IV to take advantage of some procedures I have already written,
10-character file names, longer field names, BIFs, (the list goes on).
Also, the thought of being in the 21st century with all of our code is
intriguing (and somewhat novel).

So, if anyone can point me to a list of "issues", I can take it from
there.  As always, TIA,
