SYNTAX

(char> <char1> <charN> ... )
        <char1>         -       a character expression
        <charN>         -       character expression(s) to compare

DESCRIPTION

The CHAR> (character-GREATER-THAN) function takes one or more character arguments. It checks to see if all the character arguments are monotonically decreasing. T is returned if the arguments are of monotonically decreasing ASCII value. 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 #\A.

EXAMPLES

(char> #\a #\b)                         ; returns NIL
(char> #\b #\a)                         ; returns T
(char> #\c #\b #\a)                     ; returns T
(char> #\a #\a)                         ; returns NIL 
(char> #\c #\a #\b)                     ; returns NIL
(char> #\A #\a)                         ; returns NIL
(char> #\a #\A)                         ; returns T
