Re: Why is 4+ legal?

(Redirected by "Rick VanNorman" <rick_at_forth.com>)
I wanted to report a peculiar feature of SwiftX 3.0, HC12
version. The compiler accepts n+ or n-, where n is any numeric
digit, as a legal definition, and leaves n 0 in the stack. I just caught by
this when I mistyped 4 + as 4+.
