360POO

note that the principle of ops was one of the major mainstream documents (other than the cp and cms documents) that was put into cms script softcopy form.
one of the original reasons was that the superset of the principle of operations is the architecture "redbook" ... which has a lot more stuff than what appears in the POP (possibly as much again as the pop subset. they used script conditionals to control whether the redbook would be generated or the principle of operations subset would be generated.
i think you can tell the transition from the traditionally process printed document to the cms script version by the diagram boxes. the cms script version was printed on 1403 printer and didn't provide solid horizontal lines. Later they got solid horizontal lines with the 3800 ... but in the 1403 printer period, the horizontal diagram lines were not solid.
the original cms script was done at the science center with run-off "dot" formating commands. After gml was invented at the science center in 1968 plus 1 ... cms script was enhanced to also provide processing support for gml tags.
recent posts discussion 360 storage key operation referencing the early 360 POPs (on bitsavers) and more recent pops (from an earlier part of the buffer overrun thread):
real" diagnose tends to invoke machine specific microcode whose operations aren't defined in the POP (aka the POP says something about diagnose functions are defined...
part of this was instigated by the AMD reference about provide "no-execute" support as part of buffer overflow exploit countermeasure (i.e. it doesn't eliminate the buffer overflow ... but it prevents an attacker from utilizing the buffer overflow in performing certain kinds of system exploits)
If one were *very* careful there were a few specialized situations in which a customer could...
