The official name is PL/I (as specified by the ANSI standards).  It
stands for "Programming Language One".  The "I" is a roman numeral.
Using an arabic one is incorrect.  Before PL/I, it was briefly called
NPL for "New Programming Language" but the acronym conflicted with Net
Propulsion Laboratory.  "PL/1" is incorrect but used so heavily that I
don't bother correcting people.

Another issue with the acronym NPL was that it conflicted with the National
Physical Laboratory (NPL, Teddington, UK). This was more significant, if I
recall correctly, because the first PL/I compiler was developed at Hursley
Park near Winchester (England).

I also seem to remember that IBM toyed with MPPL (Multi Purpose Programming
Language) for a while but deemed it too ugly, and that when they finally
gave up trying to think of a nice name and plumped for PL/1 they copyrighted
PL/2 to PL/100 just to be on the safe side (but not PL/M or PL/360 :-)
