Yes, general registers go in the new RB, PSW in the old. Whent the task is not running the newest RB holds the PSW and the TCB holds the general registers. I havent checked how the top halves are handled.

Just for clarity sake Just ran a small test For the interrupt PSW which in the case of some PRB s might have a cde The registers that go along with that RBOPSW Are always in the next rb Regardless of the cause of the interrupt Hope this is right Thank you very much all > On Feb 4, 2024, at 11:49 AM, Seymour J Metz <sme...@gmu.edu> wrote: > > Yes, expressed in hexadecimal.
