Bob, >From the POP quote you've posted earlie:
"the value in bit positions 64-103 of the clock (bit positions 72-111 of the storage operand) is always nonzero" This is because, a single "machine" [identified by TOD Programmable Register, bits 112-127] may have multiple CPUs - so the bits 64-103 are to make sure concurrent subtasks running on *different* CPUs within the same "machine" won't see the same STCKE value. -Victor- On Thu, 26 Feb 2009 16:28:17 -0500, Bob Rutledge <[email protected]> wrote: >Assuming that the TOD Programmable Register uniquely identifies a machine in a >parallel sysplex and given that successive STCKs yield different values on a >single machine, why not STCKE to get the TOD Programmable Register and STCK to >get a "reference number".
