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)
