Then what happens if the instruction starts at address x'00010FE' and address x'0002000' is either (1) fetch protected in a different key than the PSW key (assuming PSW key != 0) or (2) it has never been "getmained" and so is not a valid virtual address? That would have to be an S0C4 on instruction fetch. But wouldn't that have an ILC of 0? -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
