Description

§

(string->list string)
(string->list string start)
(string->list string start end)
(list->string list)

Domain: It is an error if any element of list is not a character.

The string->list procedure returns a newly allocated list of the characters of string between start and end. list->string returns a newly allocated string formed from the elements in the list list. In both procedures, order is preserved. string->list and list->string are inverses so far as equal? is concerned.
