Thanks for your reply.Now I am more clear about it. with ASN reuse facility,PT and SSAR are replaced by PTI and SSAIR,PTI and SSAIR will check the instance number.More information(like A/S instance number) was stored in linkage stack so that PR can return control to exact right address spaces..
>But it does not >prevent a workunit which previously issued the PC from being >dispatched with that ASID as PASN or SASN. yes,this could happend in ordinary ASID. but I can't figure out how the address spaces started with REUSASID=YES prevent this from happenning. or the same thing also will happen in reusable address spaces?
