Subject: questioning let

Message-ID: <4B8500C7.3010209@online.de> (raw)
Hi,
behaviour of the example code below puzzles me. Would
expect setting of arg by external function, but inside
`let', recognised. But remains `1'.
(defun arg-setting ()
(interactive)
(let ((arg 1))
(message "%s" arg)
(arg-extern arg)
(message "%s" arg)))
(defun arg-extern (arg)
(setq arg (1- arg)))
Any help?
Thanks
Andreas
