Pascal (Turbo Pascal on a PC) was my second programming language after Assembler and some C (had a copy of Aztec-C compiler) on an Amiga when I was 17ish. Pascal taught me modular programming, breaking down largensystems. I‘d written my own matrix calc library and would program animations for my physics class. And I learned the basic concepts of OO. It was a joy to program in.
