COBOL supported sequence number in columns 1-6. I believe all the card based languages supported sequence numbers somewhere in the card.
I'll never forget this story. My first semester of college, I had a really awesome intro to programming class with a professor who was part of the original team that brought CAD to desktops in the 70's & 80's, SUPER cool lady. She told us about one of their final programming exams on punch cards...her classmate was watching to class with hundreds of them in a stack, tripped, fell, dropped ALL of them, and just collapsed in a heap crying. There weren't any home printers back then, so they weren't labeled with a numerical order sequence. Ever since then, I adopted two habits:
1. I mastered the quick-save shortcut (ex. ALT + F + S in Word) & anytime I'm done with a chunk of work, I do my little keyboard-shortcut jig to force a save (this includes video games, haha!)
2. I save a duplicate copy at the end of day (if you don't have 2 copies, you don't have backup! RAID doesn't count!!). I saw too many people have their floppies die (back in the day), their USB stick not work, their laptop boot drive die, etc. I had a friend lose his PhD thesis that he had worked on for YEARS because his laptop's drive died beyond repair. These days, I'll often just drag a backup into an archive folder on my Google Drive or just email myself a copy.
Those two behaviors have saved me many, many times when things go haywire! Also, cool website!!
