PL/I

1972

Took a programming class for high school students at Columbia. PL/I on an IBM 360. My only experience with punch cards!

Assembly

1973–1974

Symbo C assembler on a Monrobot XI at my high school. I wrote a football simulation game.

Dartmouth BASIC

1974–1979

Dartmouth was rarity in the 70's in that every undergraduate was allowed unlimited, free computer use. Basic was invented at Dartmouth and that's the language I used while I was there.

Algol 60

1976

I took an undergraduate programming course at Dartmouth that was taught using Algol instead of the ubiquitous DTSS BASIC, because the professor wanted us to use structured programming techniques and BASIC didn't get beyond IF GOTO until sometime in the 80's.

Commodore BASIC

1982–1988

Used it on a VIC-20. Wrote a word processor (with output to an IBM electronic typewriter) and an electronic BBS system for ham radio teletype use.

6502 Assembly

1982–1984

Wrote a device driver so my VIC-20 could print to an IBM electronic typewriter.

DIBOL

1983–1987

DIBOL stood for DIgital Business-Oriented Language and was DEC's answer to COBOL, although the syntax was more BASIC with record definitions. My first real programming job was doing DIBOL on Micro PDP-11's in the mid-80's.

1985–

I bought a copy of K&R at the bookstore in Littleton, NH and got a copy of Eco-C for my Xerox 820 CP/M machine. I still do some C programming today, 25 years later.

DCL

1985–1993

Lots of DCL scripting (inclding a basic version control system) before moving from VMS to PCs. Didn't have a decent scripting environment again for years, until I started using Unix/Linux.

VAX BASIC

1988–1990

BASIC was one of the most popular languages on VAX/VMS systems in the 80s. I didn't much care for it and was glad to leave it behind.

FORTRAN 77

1990–1992

Did some shop-floor control and monitoring of manufacturing systems using VAX FORTRAN.

OPS5

1991–1992

Ported a manufacturing expert system to VAX OPS5 and interfaced to our existing FORTRAN systems.

C++

1991–

My biggest C++ project was probably a toy operating system written for CS 502 while working on my Masters at WPI. This was in Turbo C++ on a PC/AT clone. I interviewed for a C++ programming job in 2004, but I didn't get it, thank heavens!

PowerScript

1992–1995

Spent a few years doing PowerBuilder, but wasn't sad to let it go.

LISP

1993

Used it to do natural language processing for my grad school AI course. I liked it, but never got to use it again. I need to try Clojure one of these days.

bash

1995–

Java

1995–

I started using Java in late 1995, before Java 1.0 was released.

XSLT

1998–2005

I was an XML early adopter and did a lot of XSLT at one point. Not so much lately, but I wouldn't be surprised to see another use pop up some time.

2002–2004

The startup I was working at decided that we should move off of Microsoft's Java implementation and get with the program--thus C#. Nice tooling and great integration with Windows APIs, but since that company folded I've never gone back to it.
