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 couple of things are included here that aren't strictly programming languages (e.g. HTML, RUNOFF), but they are all computer languages of some sort.

Current regular use

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

SQL
RXML
Ruby
Python
HTML
sh/bash (Bourne shell, Bourne Again Shell)
Emacs LISP
awk
sed
make (with and without GNU extensions)
csh

Recent extended experience

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

C
C++
WOOL (another LISP)

Previous extended experience

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

Scheme (STk and the OO version STklos)
Expect (TCL)
PDP-11 assembler
TeX/LaTeX
.zwgc.desc
Zeta LISP (an early OO LISP)
MacLisp
M4
GNUplot
PostScript
TECO (RT-11/RSTS dialect)
RATFOR
FORTRAN-IV
TJ6
DCL (both VMS and RSTS variants)
COBOL
NEAT/3 (NCR Century assembly)
VAX assembler
MUMPS
RUNOFF
Nova assembler
XDP-1 assembler (an eXperimental Display Processor, main CPU similar to PDP-1, plus vector display processor)
PDP-8 assembler
Focal
Basic
Basic-Plus

Basic experience

These are languages which I have learned and written programs in, but no substantial sized projects.

PDP-10 assembler
Pascal
Algol
Scribe
CLU
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
8080 Assembler
68000 Assembler
TECO (ITS variant)
Smalltalk
Bolio
