OK, so how many of you youngsters remember IBM punch cards, keypunch machines, and card readers? Each punch card could hold 80 characters. I recall gathering with a few grad school friends up in our office. We'd go to the computer center, submit our jobs, walk back to the office, play a few hands of pinochle, and drink a little beer. We'd then go back to the computer center, make any changes we needed to make, and submit our jobs. We did it at night because it could take hours to get results back during the day. BTW, the output was on big wide sheets of paper. I know, I'm a codger.
