del!

[Denys Duchier <Duchier@YALE.ARPA>]

Here is the definition of DEL! as taken from the source file LIST2.T

(DEFINE (DEL! PRED OBJ LIST)
  (COND ((NULL-LIST? LIST) '())
        ((PRED OBJ (CAR LIST)) (DEL! PRED OBJ (CDR LIST)))
        (ELSE (SET (CDR LIST) (DEL! PRED OBJ (CDR LIST)))
              LIST)))

I assume this answers your question.
