Syntax
- (char= char1 charN ... )
- char1 - a character expression
charN - character expression[s] to compare
returns - T
if the characters are of the same
ASCII value,
NIL otherwise
Note: case is significant with this function
Description
The 'char=' function tests if all the character arguments are equivalent.
T is returned if the arguments
are of the same ASCII value,
NIL otherwise. In the case of two
arguments, this has the effect of testing if 'char1' is equal to '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) => NIL
(char= #\a #\b #\c) => NIL
(char= #\a #\a) => T
(char= #\a #\a #\a) => T
(char= #\a #\a #\b) => NIL
(char= #\A #\a) => NIL
(char= #\a #\A) => NIL
