I am passing in command line arguments to my Lisp program and they are formatted like this when they hit my main function: ("1 1 1" "dot" "2 2 2")

I have a dot function and would like to call it directly from the argument, but first I must strip the " characters.

I tried variations of this function:
(defun remove-quotes (s) (setf (aref s 0) '""))
to no avail, Lisp complains that "" is not a member of base-char.

Thanks!

Why is Lisp useful?

Lisp obviously is an advantage for the AI stuff but it doesn't appear to me that Lisp is any faster than Java, C#, or even C.
