Languages I know
Language	Proficiency
ACP and PARS	now decrepit
ALGOL 68	rusted shut
APL	wrote two programs, but I can't read them
BASIC	good
BASIC (other flavors)	so so
BPL	one of the authors
C	middling
C#	less then C
COBOL	OK   (I never let anybody know, lest I'd get roped into coding)
EXEC	proficient
EXEC2	proficient
FORTRAN	productive, those were the days
Fortran	was good, now rusty
GML	pretty good, wrote several CMS tomes in it
GPSS	ok, mostly forgotten
HPL	one of the early authors
IBM assembler and macros	proficient
IRAP	author
Java	poor, but dangerous (gun, foot)
JCL	good
JOVIAL	used it thrice
KEXX	proficient
Kingston FORTRAN II	proficient
Modula-2	very rusty
MUMPS	used in '69, forgot everything
Pascal	beginner
PL/I	good to gooder
QBE	defunct
REXX	proficient
SAS	ok
Script/370	good
Script/VS	good
Snobol	was ok, but non-functional
SQL	not so good anymore
Viatron FORTRAN IV	was one of the authors

ACP and PARS   ─── I was part of the team that first implemented the Passenger Airline Reservation System for a hotel/motel business   ─── a motel room is just a huge seat (chair) with a bed, alarm clock, TV, ice bucket, and a personal bathroom with soap and towels,   ···   but doesn't fly anywhere.

APL   ─── still bemuses me.

BPL   ─── (Basic Programming Language)   was a Honeywell subset of the PL/I language   (I was one of a dozen or so programmers/authors).

HPL   ─── (Honeywell Programming Language)   was a subset of PL/I   (similar to above)   and was to be used for Honeywell's new computer   (code name unknown)   ───   it was never built, but from what I could glean from the specs, it would have used HPL as it's native [machine] language and seemed to have some of the characteristics of IBM's FS system   (and apparently, suffered the same fate).

Kingston FORTRAN II   ─── (locally called FORTRAN 2.5)   was for the IBM 1620 with a lot of FORTRAN IV capability.

Viatron FORTRAN IV   ─── was the FORTRAN compiler for the Viatron home computer (I was one of the CUC authors of the compiler and libraries; CUC was the Computer Usage Company, at that time, the oldest software company in the USA)   and had it's fingers in writing some of the routines for IBM's TSS, which enabled CUC to write the first non─IBM book on writhing/coding assembler for the IBM/360.

I also update the   English Wikipedia page for   REXX   from time to time.
