It says that a sequence of <alphanumeric> characters that begins with a character that cannot begin a number _is_ an identifer. It doesn't require anything _not_ to be an identifier, except by requiring it to be something else. Thus, Guile is kosher if it accepts '-a as an identifier, but your program is non-portable if you ask it to. -- --Keith This mail message sent by GNU emacs and Linux. Food, Shelter, Source code.
