...and don't forget doing those programs on punch-cards! ...Wasn't THAT fun?
What's a "punch card"? We have tens of thousands of them at the office, relics of another time. They are great used as notepads. LOL!
Honestly, I've heard stories from the older guys telling us about those days. It must have been hell! /salute
Before my time. But I remember watching a sibling building a FORTRAN program on cards for a college assignment. The notion of subroutines arose from the punch card days -- the pros would have a rubber-banded deck of cards for square root, pi, whatever, and use 'em over and over.
