Do you remember the boxes that the punch cards came in, those 12-14 inches deep boxes that held one hell of a lot of cards? I've seen applications and data for applications stored in several hundred of those boxes. Each card was numbered, but if you ever dropped a box, it took hours to reorder them. One old hand taught me the magic marker approach -- because sooner or later you would drop one, or just let it slide off the desk. The bad thing was if it happened to two of more boxes at once.
I found you have to comment the hell out of every program you write, regardless of language. Because even if 6 months passed, you wind up spending time trying to re-figure out your own logic, when a short comment would have saved you potentially hours. It's a lesson I hammer into my students.
IIRC, we had a card sorter that could read the card number as sort by that criterion. It would take a few passes to sort out a big stack...say ONE of those boxes.

BTW...I guess you were still scr#w#d if you dropped two boxes at once.

Re: comments. Yes that is true, but in Basic I could usually figure out what I was trying to do with minimal comments. C otoh, was notorious for being hard to decipher later on. My prof in C called it a "write only language"...even though he really liked programming in C.

You put the label of TORTURE in there. See somewhere deep inside you, your soul knows that being separated from God is torture. I said nothing of torture.
You did not need to-- for in your arrogance you ASSUME that YOU are not the one subject to eternal torture pit.

And in your arrogance, you express DELIGHT at the revenge fantasy that MOST OTHER PEOPLE will be so tortured-- in a "lake of fire".

I am quite familiar with your sort-- old news.

Aaaah, the beauty of the card-sorting machine.

If you numbered your cards in the extreme-right-hand portion (I always did-- the first go-through, skipped by 1,000's on really big projects.-- put a comment mark in front of the number). Let's see--that was for PL-1.

For FORTRAN, I just numbered them as required, in the first 7 or 9 columns.

Then, into the card-sorting machine....

It had an input hopper, some switches and 10 bins.

Each pass through the machine sorted by whatever value you set on the switches, i.e. sort by the 100'ds first, then by the 10's then by 1's. At least that's what I remember from 25 years ago...

I can recall one project taking quite a number of passes....

Sort by hand? Not if there were more than 100 cards, not if I could help it.

At the very end, I was using one of those new-fangled "terminal" thingys-- green letters on a black screen. I would "punch" my projects, once composed "virtually".

If I dropped the box-- onto the recycler shelf it went, and I'd re-punch it.

Hey! It was college! <heh>

LOL! I didn't see this one--

yes card sorters were cool.
