I started setting it in MVS/ESA V3, which is still a very very long time ago. Since then we've had a couple of MVS/ESA V4 and MVS/ESA V5 versions, 10 OS/390 releases and 11 (now 12) z/OS releases. So I hope there isn't any ISV software around that depends on SWA=BELOW. When I made the "big leap" sometime during MVS/ESA, I left one JOBCLASS with SWA=BELOW for anything that may have required it (now JOBCLASS can be changed on the fly anyway). There could be some home grown program that has a problem, but after you make the change, it is easy enough to backout via operator command if you run into a problem. If it is something you can't fix or don't want to, then leave 1 jobclass with SWA=BELOW. Mark --Mark is right. When it first came out (early 90(?)s) quite a few products has issues. One company (who will remain unknown) gave us a 3 month date and even then it was iffy. Luckily they supplied the source to the module in question and I had it working the next day. I called them up to let them know it could be done in less than 8 hours. They had the nerve to ask me for my fix, I told them we were paying them lot's of money for support and they would have to come up with some money for me. I didn't expect them to say yes and they deferred. The next IPL we put swa above the line for everyone. The other vendor that weren't as forth coming as I had hoped took 6 months. I was not a fan of the company from then on and actively champaigned to drop the product. About a year later we found another vendor and went with them.The fix was pretty easy IIRC (at least in the source of a couple of vendors code I looked at. The trick was minor and I think any assembler coder could have done it without even trying hard.Ed ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
