When I was in Jr. High, we had an Atari 400. Mostly I used it to play Missile Command and Star Raiders, but it also came with a BASIC cartridge.
In the back of the manual were four BASIC programs. The first three were very simple, stuff like a loop that prints your name 10 times and then exits.
The last program balanced your checkbook. It was 4 pages long. I laboriously typed it in, hunt-and-peck style, which took hours... then I hit "run".
Nothing.
I couldn't debug it. Not only did I not really understand software, I didn't have a checkbook — hell I didn't even know what "balance your checkbook" meant.
We didn't have the exorbitantly expensive Atari floppy disk drive, nor the cassette drive, so I couldn't save my work. Still, I left that BASIC cartridge in there for several days, foregoing my games, because I didn't want to lose my investment.
Eventually, I turned off the computer and the program disappeared forever.
I didn't program again for 20 years.
