QBasic was my first programming language. I wrote an "operating system" called QWIN using it when I was 7 years old. It had a fake POST with a rising tone and some atonal beeps followed by a series of unnecessary pauses and prompts before getting to a text-based shell (you read that right - QWIN had no windows) which was a pile of spaghetti driven by IFs and GOTOs with arbitrary labels. I was afraid of GOSUB and loops of all types so the embedded unlicensed Pokemon text adventure was nothing more than a series of fleshed-out decision trees until you reached the end. My screensaver that drew random lines used a static seed for the RNG so it was the same every run. Fun times.

My best good friend still has a copy of it someplace on a floppy disk because we would run it on the computer that he put together out of spare parts on a piece of plywood. Thankfully he has a family and is too busy to dig it up and send it to me so I'm spared the embarrassment that would come with seeing it.

I'm always happy to see projects like this and OHRRPGCE where people did something useful with the language.
