Thank you all for the input. Sounds like we can run zVM 4.4 on the z9 - no problem. I used Q CPLEVEL and it shows us running 64 bit: q cplevel z/VM Version 4 Release 4.0, service level 0403 (64-bit) Generated at 01/12/2006 15:50:57 CDT IPL at 01/15/2006 20:09:16 CDT So, the 64 vs 31 bit possible problems is not an issue either. prg Phillip Gramly Systems Programmer Communications Data Group Champaign, IL
