Re: 64 bit question
Why not just try to get memory above the line, using IARST64 REQUEST=GET, and check the return code? http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IEA2A9B0/4.1 Or, you might check the CVTV64 bit in the CVTOSLV2 flag field of the CVT (CVT macro), after checking that FLCARCH is non-zero in the PSA (IHAPSA macro).

Re: 64 bit question
Are we not talking about a rather small, even exiguous, population of mainframes under z/OS that do not make AMODE(64) virtual storage available? Its unmediated, direct use by applications may still be exiguous too, but its mediated use by DB2 and the like is now substantial. John Gilmore, Ashland, MA 01721 - USA

Re: 64 bit question
Scott, I find your comment on 24 bit interesting as I had a new client we were in talks with who wanted us to code in C because assembler programmers are few! So I called one of our current clients to see if they have the C run modules etc. and he said Where do I look? and I said Don't bother, I've heard enough already!. So, you're right. Let's not get started!

MVS issues STFL or STFLE to save the information at location 200 (X'C8') If you're running on a z9, the hardware supports 64-bit addressing. For that matter, if you are running any release of z/OS higher than 1.5, you have to be on a z/architecture processor. -- Tom Marchant
