Well, I would, since I did it. The IPL CPU's LCCA and PCCA have to start out below 16M, because they are created before DIAGxx is processed. When we subsequently bring other CPUs online during Master Scheduler Initialization, if there is at least one other online CPU, we configure the IPL CPU offline and back online so that its LCCA and PCCA can be located as directed by DIAGxx. If there are no other CPUs online, then of course we can't do that. Jim Mulder z/OS System Test IBM Corp.
