Thanks, Greg, for the pointer to the presentation. I did not read anything
which would contradict my understanding. I conclude below text, which I cited
previously, needs some rework. I' ll submit an RCF.

order in which the control program selects jobs for execution because that order is selected
on the basis of address space dispatching priority. Once the control program selects an
address space for dispatching, it selects from within the address space the highest priority
task awaiting execution. Thus, task priorities may affect processing within an address
space."
Sigh... it's descriptively true (most of the time), but isn't accurate
with respect to the implementation. To rewrite it to be accurate to the
implementation would probably turn the sentence into a new chapter.
