There's been discussion of this topic before on either IBM-MAIN and/or the Assembler post place (can't remember its exact name). Check archives of both. Bottom line is that code can run above the bar if you put it there yourself and if that code never gets interrupted, as z/OS interrupt handler save areas are not yet enhanced for the larger registers, PSW, etc. I bet an IEFBR14 would work, since it just might finish executing before any interrupt occurred, but that's always a gamble.
