Sorting a list of words in LISP!

ANSI Common Lisp has a sort function and a few string comparison functions.

Code:

(sort sequence predicate &key key)

(string< string1 string2 &key start1 end1 start2 end2)

(string> string1 string2 &key start1 end1 start2 end2)

(string-greaterp string1 string2 &key start1 end1 start2 end2)

(string-lessp string1 string2 &key start1 end1 start2 end2)

To sort a list of strings in ascending order try this:

Code:

(sort '("foo" "baz" "bar") #'string-lessp)
