Interesting...

How old is your "Stage 3 exit Effector Logic" manual? (I'm guessing
at least a couple of decades.) I *think* that the TCBNOIRB flag might
be newer than your manual.

I don't know when it was introduced, but I became aware of TCBNOIRB
only within the past year. The TCBFX flag I've known about for several
decades.

Is it possible that TCBFX is used to suppress the scheduling of all asynchronous exit for a task, whereas TCBNOIRB specifically suppresses IRBs but not SIRBs. Stage 3 exit effector logic manual indicates TCBFX=1 prevents all asynchrounous scheduling to the task but has no mention of TCBINOIRB.

Wow, it actually dated back 1981, 1983. I do not even realize TCBNOIRB didn't exist then. Do you know what z/OS version it was introduced?
