1975–
1976–1987
On IBM 360's using punch cards, and (much later) HP 3000's.
1979–
1980–
1982–1983
At university in 1982, and then, conveniently, commercially for a summer holiday job 1982/1983.
1983–1988
Used in college for one semester then eventually at my second job wrote some COBOL code to test our HDBMS API. Never wrote any non-academic applications in it, don't like it.
1984–1987
1985
Worked on a COBOL project for 7 months. Managed to find a new assignment after the project manager asked me to stop using dynamic memory allocation because "it was too tricky" (this was a non-standard feature in Wang VS COBOL).
1985–1986
1987–1988
University business course, horrible language.
1987
1988–1989
Actually had to take 2 courses in this while in college. Swore I would never use this in a job. To this day, I haven't.
1989–1990
Nasty, and nobody would like to admit this one, but a fair number of large corporations loved it. Hence it was on the curriculum at Polytechnics.
1990–1994
Purely educational.
1995–
1996–1997
Worked on a banking app for a few months and built a full video store app with this. Almost went blind because of this language: ALL CAPS CODE and thousand lines methods. It took me years to recover from this...
1996–1998
If you ever saw AcuCobol running in a browser, I'm to blame
1996–1997
My experience with Cobol is limited to my exposure in a CS class.
1996–1998
RM-COBOL
1997
For school. This language almost made me hate programming.
1998
I was the poor guy in charge of doing the project in this language for a university course... and I did like it, but what did I know at the time....
