Bruce, I'm sure you'll have many suggestions for RPG III to RPG IV conversion... I think the issues you've acknowledged in your email are the bulk of them. The single biggest issue for most people, that I've found is the OVRDBF question. If you are going to convert your CLP's to CLLE's, then changing the OVRDBF to *CALLLVL may help you avoid some surprises. If you leave them as CLP's, then you need to change the overrides to *CALLLVL or *JOB to avoid loosing them when CLP calls RPG IV which subsequently calls CLP. -Bob -----Original Message----- From: rpg400-l-bounces@xxxxxxxxxxxx [mailto:rpg400-l-bounces@xxxxxxxxxxxx] On Behalf Of Bruce Guetzkow Sent: Tuesday, October 12, 2004 10:53 AM To: rpg400-l@xxxxxxxxxxxx Subject: Converting to ILE 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.
