Curious Dave if you have a particular piece of
documentation in mind?
I'm mostly finding the term "keyletter" in SCCS manpages and pages
related to the lp print system. This nomenclature appears to go back as
far as Release 4.0 of SCCS/PWB on February 18, 1977, it is also used
throughout the PIB regarding this release.
You're right; it was SCCS, not SysV. Dunno what I was thinking...
Thanks.
