Was that the computer punch cards we use to use? A small program would have a thousand cards? Is that this guy?
Everything was punched cards in those days. We’d have one day turnaround and you’d better have put sequence numbers on your cards or the comp center would just run dropped decks as is for your one and only chance. Always put a chill down my spine to see dropped decks at the curb in the puddles when the operators would bump the trolley with the decks as they went between programming buildings and the main computer building.
That was probably Fortran (Formula Translator). Doing programs on punch cards led to the notion of subroutines — a slightly worn set of cards in a rubber band with the top one labeled in felt tip, “Pi” or “Square root”, was part of pro programmers’ tool kits. :^)
