语法
注释
注释可以像传统的Lisp分号分隔，
(car mylist) ; Comment from semicolon to end of the line
或者像C-样式注释
/* Comment */ car(mylist) /* Another comment */
程序定义
;; C style
procedure (factorial(n)
if ( n <= 1 then
1
else
n * factorial(n-1)
)
)
;; LISP style
(procedure (factorial n)
(if (leqp n 1)
then 1
else (times n (factorial (difference n 1)))))
;; Hybrid style
(procedure (factorial n)
(if n <= 1
then 1
else n * (factorial n-1)))
