Well if the intent is to support above the bar storage, then GETMAIN or STORAGE won't help, as they only manage 24 or 31 bit storage. Requests for above the bar storage require usage of the IARV64 service. Since the storage is owned by the address space, this service will still require (at some point in its processing) the local lock, so suspensions due to lock unavailability will still come in to play.

As I recall the original question it was how to load a large VSAM file into memory above the bar because if loaded into CICS DSA, the region went SOS. Most people there said to rearchitecture the application to use some other, supported, method. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
