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.
That's what the sequence numbers in columns 73-80 are for. You just put it in a card sorter 
JimboZA:
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.
That's what an exacto knife and scotch tape are for. In addition, I recall occasionally having to program in Pascal on an 027 card punch when the 029 card punches were busy, and having to multi-punch things like semicolons.
