I started college in 1989, so I missed the punch cards, but I do recall sending mainframe jobs off and waiting several minutes (depending upon how busy the labs were) to hopefully see a return code of 0000 (perfect!) or no more than 0004 (which meant "it compiled, but warning!"). 0012 or 0016 meant you were fixing and resubmitting. COBOL, FORTRAN, Waterloo Pascal, Assembler all come to mind.
