1967–1973
1972
Took a programming class for high school students at Columbia. PL/I on an IBM 360. My only experience with punch cards!
1973
Only used in a class to write an assembler, loader, and interpreter. Back in the days of doing your homework on cards and submitting them through cubbyholes for the 360 Model 155 to get to, maybe 4 hours later, on good days.
1977–1978
The required first language for CS students at WVU when I was there. Abandoned it for assembler as soon as it was possible to do so.
1979–
1981
Yay for big iron at WVU. Mostly programmed this with punch cards.
1982–1984
Learned in high school, had a bit of practice, that's all.
1983–1988
My first commercial programming job, on a Stratus fault tolerant mini computer. It was a PL/1 subset implementation, which is pretty good actually for large scale software.
1985–1987
In my first job my first task was to buy a compiler for the Data General MV10000 -- the choices were FORTRAN, COBOL, or PL/I. The choice was easy...
1985–1989
1986
1989–1991
I used PL/I working for Boeing on an 8051 system for the thrust reverser/landing gear control unit. Don't blame me! My job was to review the code and I told them it would happen. (!!! 3x) Later, I used it for technical reviews when working for some victims' attorney.
