+BASIC = Beginner's All-purpose Symbolic Instruction Code

+> At least for the people who send me mail about a new language that they're
+> designing, the general advice is: do it to learn about how to write a compiler.
+> Don't have any expectations that anyone will use it, unless you hook up with
+> some sort of organization in a position to push it hard. It's a lottery, and
+> some can buy a lot of the tickets. There are plenty of beautiful languages
+> (more beautiful than C) that didn't catch on. But someone does win the lottery,
+> and doing a language at least teaches you something. \
