principles of operation was similar but different ... one of the first
mainstream publications moved over to cms script. the full document was
called the architecture redbook ... for distribution in red 3ring
binder. cms script command line argument would either format the full
redbook or the principles of operation subset ... the full redbook
included justifications, alternatives, engineering considerations, etc
(which about doubled the size of the document)
archeological: cms script was originally re-implementation of CTSS
runoff for cp40/cms (science center had gotten 360/40 and made hardware
modifications to support virtual memory) ... which became cp67/cms when
science center got a 360/67. (gml) tag processing was added to cms script
after gml was invented at science center in 1969 ("gml" are the 1st
letters of the 3 inventors last name).
