unset

unset Unsets a set of variables
Usage
unset <variable_list>
Description
Unsets the specified list of comma separated variables. It is equivalent to assigning the default empty value to each variable on its own: just does it all at once. Note that KVIrc automatically frees the local variable memory when they go out of scope and the global variable memory when KVIrc terminates.
Examples

%a = pippo
%b = 1
echo %a %b
unset %a %b
echo %a %b
