Assign values to variables by using “setq”. Values can be arbitrary
expressions:

(setq cmd-excl "value")

(setq cmd-excl (read-from-minibuffer "exclude: "))

If you write “(cmd-excl…” the lisp interpreter will try to call a
function “cmd-excl”.

You can declare local variables with “let”:

(let (cmd-excl cmd-incl)
(setq cmd-excl "value"))

Values can be declared and assigned to at the same time:

(let ((cmd-excl "value")
cmd-incl)
cmd-excl)

There is also “let*”:

(let ((cmd-excl "value")
(cmd-incl cmd-excl)) ; can access cmd-excl here already
; because of let*
cmd-incl)
