Like most developers I attempt to keep things in GPRs, both high and low halves, as much as reasonably possible to improve performance. Over the past 10 years I have begun using FPRs 0-7 as temporary storage buckets rather than virtual/real storage and have experienced no issues in a traditional 'batch' environment.
Now I have occasion to do the same under CICS and was wondering if anyone is aware of restrictions on FPR usage under CICS? My very limited testing has not turned up anything, and so far found nothing in the docs I've been hunting through. Thanks much, Mike
