PLUS dates from the years when a name beginning "Programming Language ...", 
especially if "..." included a "/", identified a language *expected* to be
a direct derivative of "Programming Language One": PL/I.

PL/I was a major descendant (some call it a "mongrelization") of FORTRAN
and COBOL, in addition to Algol.  Its earliest working name was FORTRAN VI,
but it was introduced as the "New Programming Language": NPL, to associate 
it with IBM's then-upcoming "New Product Line", later known as "System/360".
It remained "NPL" until the National Physical Lab (NPL) in the U.K. objected, 
resulting in renaming the language "PL/I".  That turf scuffle in 1965 
foreshadowed today's legal climate, but fortunately did not burden us with 
"PL/I (tm) International Business Machines Corporation" (cf. "Ada", "dBase").

Hmmm.  Maybe I should write "NPL (tm) National Physical Laboratory, U.K." :-(.
