You can create/destroy 64-bit virtual memory objects in 31-bit mode using the IARV64 service. But you cannot use them without being in 64-bit addressing mode any more than you can use virtual memory above 16MB while in 24-bit mode. -- - | Edward E.

Teds point is still appropriate - from the standpoint of a discussion of IEFUSI I was remiss in being less stringent in my comment than I should have been. I can only offer the (lame) excuse that I was about to head out the door and mow the yard, and maybe the excitement of such got the better of me. *NOT* Shane ... -- 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
MIGRATION 31 to 64bit IEFUSI and MEMLIMIT
Hello, I still preparing our migration to a new Z processor. Fisrtable I will turn it in 31bit and use the same exit iefusi (now limit 512MB above). Does someone could advise me for 64bit migration, which is the best thing to do : - MEMLIMIT coded or not ? - IEFUSI modified ? or not. I read that we can code Word 9. If needed could someone send me an example of his IEFUSI assembly ? Thank you for infos. -- 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

Current USI will continue too work in ARCHLVL 2 (it always runs 31-bit regardless of environment) although (obviously) lacking any MEMLIMIT awareness. MEMLIMIT is only an issue for 64-bit capable code. Haven't seen a lot of it, but it will come. Can be nominally controlled by SMFPRMxx, but complete management dictates some logic in USI and possibly JES exit(s). All, of course, site specific.
