Look what I found...

University: Punch card for FORTRAN. Batch process get your print output. Edit, shuffle and resubmit. Repeat.

Me too (WATFOR)... you forgot the "drop on floor and accidentally stomp cards" part.

I remember running back to the computer centre between lectures to fetch print out only to find it hadn't compiled due to a silly syntax error. Then there would be no vacant card punch, then late for next lecture.
