LISP programming language/Talk

---

Function CAR in LISP program returns the first element in a list.

   (car '(a b c d))
   Returns a

Function CDR would return everything but the first element in a list.

   (cdr '(a b c d))
   returns (b c d)

There are of course many variations of this.

   (cadr '(a b c d))
   Returns b

Working from the inside out is the same as (car (cdr '(a b c d)))
