The Freiburghouse PL/I for Translation Systems, which formed the basis
of the PL/I compilers for all systems aside from IBM was a new
implementation from the Multics version.
Characterizing IBM PL/I as "more than ANSI" is misleading. That ANSI
definition is actually more rigorous, and unlike IBM did not have ad
hoc extensions. Although we own the VMS version of PL/I which also is
derived from the original Freiburghouse compiler, our UNIX version
actually implements ANSI, IBM (version 2.3) and Digital as separate
dialects. I chose to keep them separate.
