There has been some confusion concerning MAPCAR.
(DEFUN MAPCAR (&FUNCTIONAL FCN &EVAL &REST LISTS)
(PROG (V P LP)
(SETQ P (LOCF V))
L (SETQ LP LISTS)
(%START-FUNCTION-CALL FCN T (LENGTH LISTS) NIL)
L1 (OR LP (GO L2))
(AND (NULL (CAR LP)) (RETURN V))
(%PUSH (CAAR LP))
(RPLACA LP (CDAR LP))
(SETQ LP (CDR LP))
(GO L1)
L2 (%FINISH-FUNCTION-CALL FCN T (LENGTH LISTS) NIL)
(SETQ LP (%POP))
(RPLACD P (SETQ P (NCONS LP)))
(GO L)))
We hope this clears up the many questions we've had about it.
