"someaddr" is the address where the 30H is. I think you'd need AL, though. If the instruction memory is not write protected or in ROM, there's nothing to prevent one's changing it on the fly.

Mitakeet, you're gonna make me brush up, aincha :p ? In days of yore, an interrupt would have negated the things in the pipeline and it would have behaved the same as if one were in debug single-step.
