My university actually taught/used Pascal in the classroom in the early/mid 1980s and I graded programs written in it. Kernighan's criticisms of Pascal on BSD are spot on - I know, I tried using it for a (more) serious project. The semester project for my Operating Systems class was to simulate an interactive operating system - in Pascal.
The system used for the class was the University's IBM 4381 mainframe running MUSIC ("McGill University System for Interactive Computing") and the version of Pascal had *lots* of libraries and features.
I was a undergraduate research assistant (working on an AI project, funded by NASA, in LISP and Prolog) and had an account on the VAX-785 running 4.3BSD and wanted to use *that* (on my schedule) instead of standing in line to use the IBM. My instructor said "sure", but I'd have to port the support libraries he wrote for the assignment. Unfortunately, the version of Pascal on BSD was just the basic language - as specified in the Language Definition book by Jensen and Wirth. Porting the code from the "richer" version of Pascal on the IBM/MUSIC to the "basic" version on VAX/BSD was simply not possible.
So, I asked my instructor if I could, instead, do the semester project in C. He said "sure", but, again, I'd have to port his libraries from Pascal to C. Now... I didn't know C at the time, but porting his code to it and doing my semester project in it was a great introduction - and I passed the class. All-in-all, this experience help me out immensely with my CS career as I do a LOT of cross-platform work in many programming languages - though not Pascal
