(cons obj1 obj2)

(car pair)
(cdr pair)
See R^4RS.
(cxr pair pattern)
pattern is either a symbol or a string consisting of a combination of the characters `a' and `d'. It encodes a sequence of car and cdr operations; each `a' denotes the application of car, and each `d' denotes the application of cdr. For example, (cxr p "ada") is equivalent to (cadar p).
(caar pair)
...
(cddddr pair)
See R^4RS.
(set-car! pair obj)
(set-cdr! pair obj)
See R^4RS.
Both procedures return obj.
(make-list k obj)
Returns a list of length k initialized with obj.
Examples:
(make-list 0 'a) ==> () (make-list 2 (make-list 2 1)) ==> ((1 1) (1 1))
(list obj ...)
See R^4RS.
(length list)
See R^4RS.
(list-ref list k)
See R^4RS.
(list-tail list k)
See R^4RS.
(last-pair list)
See R^4RS.
(append list ...)
See R^4RS.
(append! list ...)
Like append, except that the original
arguments are modified (destructive append).
The cdr of each argument is changed to point to the next argument.
Examples:
(define x '(a b)) (append x '(c d)) ==> (a b c d) x ==> (a b) (append! x '(c d)) ==> (a b c d) x ==> (a b c d)
(reverse list)
See R^4RS.
(reverse! list)
Destructive reverse.
(memq obj list)
(memv obj list)
(member obj list)

(assq obj alist)
(assv obj alist)
(assoc obj alist)
See R^4RS.
