I think your copy of OS/360 is borked, or is this one of the names
they mangled in MVS?  I have a vague memory of JCL that had those

Pronouncing spellings is bad, yes, but that is not what I was

defined either in "The design and implementation book" or in
the code comments themselves.

I was not saying Pee See Bee for pcb, I was saying process
control block.
