A string in SXEmacs Lisp is an array that contains an ordered sequence of characters. Strings are used as names of symbols, buffers, and files, to send messages to users, to hold text being copied between buffers, and for many other purposes. Because strings are so important, SXEmacs Lisp has many functions expressly for manipulating them. SXEmacs Lisp programs use strings more often than individual characters.
