Mitch Bradley's idea was good, and your idea is also good. That's the funny thing about Forth programmers --- they are always coming up with good ideas. The

It already is popular. UR/Forth has its HEADER, Gforth has its NEXTNAME, etc., etc.. As I said earlier, it is likely that every Forth system has provided some
