# char>

Type: | - | function (subr)
Source: | - | xlstr.c

## 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
