When I was younger, I decided I wanted to learn how to write games. I decided I needed to start simple, though, and I thought NOTEPAD.EXE was about the simplest thing out there. (This was in Windows 3.1.) So to learn how NOTEPAD.EXE worked, I opened NOTEPAD.EXE in NOTEPAD.EXE, and spent several hours trying to decipher the symbols' meanings.
My first attempt at coding was … unsuccessful.
