ANSI Common Lisp  14 Conses 14.2 Dictionary of Conses
- Syntax:
-
append
&rest lists
 result
- Arguments and Values:
-
list - each must be a proper list except the last,
which may be any object.
result - an object. This will be a list
unless the last list was not a list
and all preceding lists were null.
- Description:
-
append returns a new list that is the concatenation of
the copies. lists are left unchanged; the list structure
of each of lists except the last is copied.
The last argument is not copied; it becomes the cdr of the
final dotted pair of the concatenation of the preceding lists,
or is returned directly if there are no preceding
non-empty
lists.
- Examples:
-
(append '(a b c) '(d e f) '() '(g)) (A B C D E F G)
(append '(a b c) 'd) (A B C . D)
(setq lst '(a b c)) (A B C)
(append lst '(d)) (A B C D)
lst (A B C)
(append) NIL
(append 'a) A
