Thanks Kevin - I did find one with this name, which I assume is revision 
D. Over 800 pages! It should make interesting bed-time reading!

Happened to see something about the system being object-based - a term 
I've heard and used. It says the OS is not object-oriented, because it 
does not include the OO trait or feature of inheritance - seems to me, 
this isn't exactly right - I mean, everything has basic attributes of an 
object that it shares with all other objects, then there are distinction 
for things like program and files and from there, display files, printer 
files, DDS-type PFs, DDL-type tables - that seems like a lot of inheritance.

There are enough other OO characteristics the system does not have - 
seems inheritance is one it DOES have in some way - am I missing something?

Cheers
Vern
