No, you have to simultaneously compare PSAAOLD with the address space you're interested in and PSATOLD with the task you are interested in because you will find TCBs at the same address in many address spaces. One "creative" way to do this is PLO.CL where you use the ASCB address as the compare value for PSAAOLD and load from PSATOLD. If the compare fails you just skip that PSA because the associated cpu isn't executing any task (or SRB) in that address space.
Are you sure PLO can be used this way? Will the "compare" portion work against arbitrary values not serialized/updated using PLO?
