$not
$not
Performs a bit-wise NOT of a value.
Syntax
$not(char)
Parameters
char | a character string, or an expression that evaluates to a character string |
Return Value
Character string.
Comments

If the char string contains more than one character, only the first character in the string (one byte) is processed. Char can be expressed as a hex code.
