Syntax
- (char> char1 charN ... )
- char1 - a character expression
charN - character expression[s] to compare
returns - T
if the characters are of monotonically decreasing
ASCII value,
NIL otherwise
Note: case is significant with this function
Description
The 'char>' function tests if all the character arguments are
monotonically decreasing. T is
returned if the arguments are of monotonically decreasing
ASCII value, NIL
otherwise. In the case of two arguments, this has the effect of
testing if 'char1' is greater than 'char2'. This test is case sensitive, the
character '#\a' is different and of greater ASCII value than the
character '#\A'.
Examples
(char> #\a #\b) => NIL
(char> #\b #\a) => T
(char> #\c #\b #\a) => T
(char> #\a #\a) => NIL
(char> #\c #\a #\b) => NIL
(char> #\A #\a) => NIL
(char> #\a #\A) => T
