Char<

Less-than test for characters

(char< x y) is true if and only if the character code of x is less than that of y. See char-code.

The guard for char< specifies that its arguments are characters.

Char< is a Common Lisp function. See any Common Lisp documentation for more information.

Function: char<

(defun char< (x y)
  (declare (xargs :guard (and (characterp x) (characterp y))))
  (< (char-code x) (char-code y)))
