A variation on what you're describing was actually my very first experience with computers. The programs that came with my Apple IIc when I was about 8 years old weren't very interesting to me so I started poking around and playing with BASIC code.
It's kind of funny to think that at the time the sole purpose of my computer was to help me write and run programs I wrote myself.
