the code could be alot better, here is a small example
usage /ovrkillban #channel

alias ovrkillban {
if (!$ial($2)) { echo -a * /ovrkillban: IAL error | return }
var %i = 1,%addresses
while (%i <= 10) {
%addr = %addr $address($2,%i)
if ($numtok(%addr,32) == $modespl) {
mode $1 + $+ $str(b,$numtok(%addr,32)) %addr
%addr = \"\"
}
inc %i
}
if (%addr) mode $1 + $+ $str(b,$numtok(%addr,32)) %addr
}
