I started to look att www.franz.com video introduktion for LISP and
have a seen test program for let*

There is one parenthesis at the end you might want to delete.
Properly formatted it looks like this:
(let* (( x 0)
(y ( * 2 3))
z)
(print z)
(format t "~% (~a,~a)" x y))
and i was trying to write a version of hello world using let*
like this
(defun hello ()
(let* (
(USER "Anders")
(MESSAGE "Best regards"))
(format t "~% ~a ~a " MESSAGE USER)))
You should use the Lisp indenting feature of your
favorite editor.
(defun hello ()
(let* ((USER "Anders")
(MESSAGE "Best regards"))
(format t "~% ~a ~a " MESSAGE USER)))
Both works but in exampel 1 the let* last ) is after z...
But to make exampel 2 work i have to set last ) for let* after format
LET* encloses the whole form.
If not format say USER and MESSAGE is not define.
I can't understand de diffrent, can some one tell me if i make my
samting wrong
or is i a good reason for de diffrens..
