Fortran

1981–

First language. Learned by book. Later used in a variety of academic applications, but not too much.

Pascal

1981–1989

Mostly in the academic environment (high school, college).

PL/I

1982–1984

Learned in high school, had a bit of practice, that's all.

Assembly

1985–

Studied IBM/360 assembler in college. Learned some x86 assembly later.

1986–

Learned it while in college, but started extensively using it only after graduation (1991).

Turbo Pascal

1988–1991

School, internship.

C++

1991–

Mostly used in the 1990s.

Bourne Shell

1992–2003

Java

1996–

Occasional user. Standard edition as well as mobile (J2ME).

Perl

1998–

Javascript

2002–

Actively using both in commercial and hobby projects.

VisualBasic

2004–

Had to use in a commercial environment when joined a project written in VisualBasic. Now mostly rewritten in C#.NET

XSLT

2004–

They could just have used a lisp dialect. But no.

2006–

Main language at work now.

bash

2007–

Used other shells (sh, tcsh) since 1992.

PHP

2009–

Has to use in a hobby project. Avoiding if possible. Too prevalent on hosting sites to avoid completely.

Clojure

2009–

Learned about at a Lisp conference. Learning it now (2010).

QBasic

Used it very little in college and helping friends. Do not remember the dates.

LISP

First was learning it in high school on my own by books. Then was learning it in college for an AI class, again from books and manuals. Now studying Clojure.

Algol

High school only, as I recall.
