Re: HVCOMMON
Hi Barbara, I know it doesn't count as an official publication, but the additional 2gb in the high common are actually documented in the z/OS v1r10 implementation redbook (sg24-7605). Gil.

Re: 64-bit Common Storage in z/OS 1.10 (HVCOMMON)
Mark, We are in the process of updating the doc for 64-bit common apparently we missed the Extended Addressability Guide. There is information about the GETCOMMON parameter of IARV64 in z/OS V1R10.0 MVS Programming Authorized Assembler Services Reference Vol 2 (EDTINFO-IXGWRITE). Also my SHARE session 2818 - Common Storage Virtual Storage Constraint Relief (VSCR) from the August 2008 San Jose Share contains information on 64-bit Common. Let me know if you have any additional questions.

Re: 64-bit Common Storage in z/OS 1.10 (HVCOMMON)
Maybe I'm to last to figure this out ... Anyone (else) looking to download this, make sure you have java script turned on, else (using 2818) you'll keep getting referenced to paper on Herc (from Austin) ... :oops: Shane ...
