Robert,
>> In my dump R15 is zero which, if I'm right about how the instruction
works, is not an error.
depending on when it became zero. Is it the register for the address in
the RP - then the zero means use the offsets in the fields following RP
as absolute addresses- it could work, but I prefer not to use page zero.
or it is zero in the dump after execution - then the field (for the
register in the RP-instruction) that has the offset (plus the content
before the RP) pointed to something that has zero in it. Perfect ...
gut luck with bug hunting
