That is not the way 64-bit storage works in z/OS. You can request. If you request conditionally, you get a return code back if not available (such as by 'too small MEMLIMIT'). It is then up to you to request below-2G storage by the normal means. If you request unconditionally, you abend if not available. >My issue is more trying to allocate a 64 bit storage >and it failing Just about any request for storage can "fail". It is up to you to decide what to do when it does, such as 'try something else'. Peter Relson z/OS Core Technology Design
