When I was about 6 or 7 there was a complete section of my math textbook which contained informations and example on the BASIC language. We, of course, never read those chapters in class but I did anyways while bored with the actual stuff the teacher would say.

It would use a very simple and systematic flowchart representation to model control flow. The great thing about it is that once you understood < > = (also taught in the class) the whole program could be readable.

I think I was the only one to read it and pretty much got the feeling it wasn't important as nobody, even the teacher, payed any attention to it.
