Syntax
- (char-greaterp 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 not significant with this function
Description
The 'char-greaterp' 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 insensitive, the character '#\a' is considered to
be the same ASCII value as the
character '#\A'.
Examples
(char-greaterp #\a #\b) => NIL
(char-greaterp #\b #\a) => T
(char-greaterp #\c #\b #\a) => T
(char-greaterp #\a #\a) => NIL
(char-greaterp #\c #\a #\b) => NIL
(char-greaterp #\A #\a) => NIL
(char-greaterp #\a #\A) => NIL
