I don't think there's any built-in way to get a list of the arguments that were named separately in the argument list. Emacs Lisp's argument processing is very similar to Common Lisp's, and it doesn't have a way to do it, either. So you have to refer to the named arguments themselves: (defun move (x y z) (apply do-move (list x y z))) (defun move (x y z) (funcall do-move x y z)) -- Barry Margolin, barmar@alum.mit.edu Arlington, MA *** PLEASE post questions in newsgroups, not directly to me ***
