Was the number actually punched in the card, or was it only printed 
on the top of the card? Printed on the top of the card would not 
require any modification of the card reader routine, and would not 
eat up columns on the punch card. If I remember correctly, you only 
had 80/card.

If the number was punched, I could picture a program that would 
re-order the program based on the number, if the cards were messed 
up, but you would probably have needed a mini-computer to do that, 
and feed it to the mainframe.
