I guess you mean returning more than one value? Try
MULTIPLE-VALUE-BIND, taken from Common Lisp:

http://www.lisp.org/HyperSpec/Body/mac_multiple-value-bind.html

Thus you can define a function that returns multiple values:

(defun f () (values 1 2))

And get at the values like this:

(multiple-value-bind (a b)
    (f)
  (format "a is %d and b is %d" a b))
