I knew about 80 just being a standard but put into the context of punch cards it just makes sense. Same thing with cobol, max line length is 80, first seven are stripped from compile, comments start on line 7. Who thought 72 char lines were a good idea in a language? Guys that dropped a few too many stacks of cards. Thank god for the continuation character.
