Sort of makes you wonder, doesn't it?
According to: "z/VM CMS Application Development Guide Version 5 Release
1.0"
(SC24-6069-00)
(and various other manuals, including the Quick Reference Guide -- home
of lots
of good overview material in the front) filemodes 7-9 are reserved for
IBM use.
Presumably some nefarious programming schemes by Chuckie? Makes me
wonder
what I'd find by searching the CMS source code.
You would find that CMS enforces the restriction of 0-6. The phrase
"reserved" means "don't even *think* about it". There is no hint of what
our ancestors might have had in mind for 7, 8, and 9. I'm guessing
number 9 was for files backed by a quantum singularity server, allowing
them to be shared among multiple universes (up to 8) and their updates
seen instantly.
