Syntax
- (char-not-equal char1 charN ... )
- char1 - a character expression
charN - character expression(s) to compare
returns - T
if the characters are of different
ASCII value,
NIL otherwise
Note: case is not significant with this function
Description
The 'char-not-equal' function tests if all the character
arguments are different values. T
is returned if the arguments are of different
ASCII value, NIL
otherwise. In the case of two arguments, this has the effect of
testing if 'char1' is not equal to 'char2'. This test is case insensitive,
the character '#\a' is considered to be the same
ASCII value as the character
'#\A'.
Examples
(char-not-equal #\a #\b) => T
(char-not-equal #\a #\b #\c) => T
(char-not-equal #\a #\a) => NIL
(char-not-equal #\a #\b #\b) => NIL
(char-not-equal #\A #\a) => NIL
(char-not-equal #\a #\A) => NIL
