Does it have to be a different value on every call
If I understand your question, the answer is no.
You *might* use a different value to indicate the PET was released for a
specific reason, such as 0 for process work, 2 for error occurred, and 3
for terminate. Or you could use 0 for everything except for owning
address space termination (which is actually the design I would
recommend) and set flags in the control block where the PET to resume
was passed to indicate what to do.
Owning address space termination is a special case when Pause/Release is
used between multiple address spaces (which is the best reason for using
it), because if the owning address space terminates you need to know
that you were released for a very abnormal reason, possibly without that
address being able to set any flags in the control block, and handle it
uniquely.
