What do you mean by that and why do you want to know? As others have said, when your SRB is running on your CP, there can be no TCB dispatched on the same CP. Every other processor has its own PSA and any of them could be running one or more tasks in your address space at any given moment. I would suggest that you read in the Principles of Operation about prefixing and absolute addresses. OTOH, it is quite possible that none of the tasks in your address space are dispatched on any processor at the moment, even if they are dispatchable. And, of course, all of this is subject to change very quickly. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
