Add me to that list, though my Commodore machine was a PET 2000. In fact, I was young enough at first that all I could do was remove lines from other people's basic programs and see what happened. It all grew from there.

I probably started the same way. I remember spending forever typing in BASIC games from magazines and books from the local library. They never worked straight off, so a bit of "debugging" was usually required, i.e. spot the typos.
