We programmed abstract data structures in Pascal. I think we implemented quicksort. I guess I was lucky? Fun story: The first time I was truly speechless in CS in high school was when my teacher, looking at my code, told me that, for a boolean variable foo, it's not necessary or reasonable to write IF foo = TRUE THEN // whatever; "=" is comparison in Pascal BTW but rather you can just write IF foo THEN // whatever It seems trivial, even stupid now, but at the time it was an eye-opener.
