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?
ILC is 4 - the 41xx at 10FE is not part of the failing fetch. ILC must
be known to cause the S0C4
Old prog psw is 00002002
