The three-line program introduced here is nearly equivalent to the one-line namesake of this book with the only difference being that the condensed version doesn't clear the screen as in the first line of the expanded code. | + | Like many microcomputers of its day, the C64 came with a BASIC interpreter built in so that once you could begin writing programs right out of the box.
