$isEmpty

Checks if a variable is set (empty or non empty)
Usage
$isEmpty(<data>)
Description
Returns 0 if <data> is actually set to some non-empty value and 1 otherwise. Since KVIrc treats unset variables as empty ones then this function is the exact opposite of $isset.
Syntax Specification
<boolean> $isEmpty(<data:variant>)
