scheme和common lisp 区别

Scheme and Common Lisp use different names for some of the basic system functions. Many Lisp programs can be translated to the other dialect simply by changing these names (or by providing the existing names as macros or functions). Compatibility packages exist to allow programs in one dialect to run in the other dialect.

The following table gives correspondences between Scheme functions and the equivalent Common Lisp functions.

Scheme:	Common Lisp:
(define (fn args ...) code)	(defun fn (args ...) code)
begin	progn
set!	setq
eq?	eq
eqv?	eql
equal?	equal
number?	numberp
zero?	zerop
pair?	consp
null?	null
display	princ
write	prin1
newline	terpri
(list-tail lst n)	(nthcdr n lst)
(list-ref lst n)	(nth n lst)
subset?	subsetp
map	mapcar
for-each	mapc
vector-ref	aref
vector-set!	(setf (aref ...) val)
substring	subseq
#t	t
#f	nil
'()	'() or nil
