Computer Languages

This is a list of the computer languages I know. It's in descending order of current familiarity. I find I can learn most computer languages in a very short time (hours to a day at most for simple tasks). A few things are included here that aren't strictly programming languages (e.g. HTML), but they are all computer languages of some sort.

Current regular use

These languages are ones that I currently use on a regular basis.

HTML
sh/bash (Bourne shell, Bourne Again Shell)
Emacs LISP
M4
awk
sed
C
WOOL (another LISP)
make
csh
SQL

Recent extended experience

These are languages I have recently (within the last five years) written a large program or system in, but have since stopped using.

Scheme (STk and the OO version STklos)
Expect (TCL)

Previous extended experience

These are languages in which I have written large systems at some time in the past, but have not used within the last 5 years.

PDP-11 assembler
TeX/LaTeX
.zwgc.desc
Zeta LISP (an early OO LISP)
TECO (RT-11/RSTS dialect)
RATFOR
FORTRAN-IV
TJ6
DCL
COBOL
NEAT/3
VAX assembler
MUMPS
XDP-1 assembler (similar to PDP-1)
PDP-8 assembler
Focal
Basic
Basic-Plus
RUNOFF

Basic experience

These are languages which I have learned and written programs in, but no substantial sized projects. Some of these were languages used in classes at MIT, in which the class assignments were written, but which I never used again.

PDP-10 assembler
Pascal
Scribe
Pike
Macsyma
APL
IBM-360 Assembler
JCL
HACTRN

Read-only languages

These are languages with which I am sufficiently familiar to understand programs others have written, even to the point of making basic modifications, but have yet to write a real program in, only toy programs.

PERL
C++
8080 Assembler
68000 Assembler
TECO (ITS variant)
Smalltalk
Bolio
