NTHCDR

Major Section:  PROGRAMMING

(Nthcdr n l) removes the first n elements from the list l.

The following is a theorem.

(implies (and (integerp n)
              (<= 0 n)
              (true-listp l))
         (equal (length (nthcdr n l))
                (if (<= n (length l))
                    (- (length l) n)
                  0)))

The guard of (nthcdr n l) requires that n is a nonnegative integer and l is a true list.

Nthcdr is a Common Lisp function. See any Common Lisp documentation for more information.
