I guess I had a major memory failure. I got into the books and you are correct. Even a global SRB is scheduled into an address space. It's just that global SRBs are dispatched before address spaces.
I could have sworn that z/OS (MVS) had _something_ which did not run in an address space. And the books all seem to say that the program needs to be in globally addressable storage. Which seems strange to me if it an SRB runs in the context of an address space, why can't the code be in only that address space? I eagerly await being enlightened by the more knowledgeable of our members. Maybe I should stop doing all this Linux reading. But I love looking at source and learning. With no source and no PLMs any more z/OS is becoming very boring to me; a windows admin could do it. "Just say NO! to OCO!" <grin/> Hopefully nobody starts up a thread on why IBM did it. They did it; they had the right to do it; I don't have to like it.
