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