no need to set vars on this, and un instead of that huge random letters you can just use
$r(A,Z)
here try this
menu channel {
.Hide:{ mode $me +H | sethost AG- $+ $r(111,999) $+ $r(A,Z) $+ $r(A,Z) $+ $r(111,999) $+ <ENTER YOUR USUAL ADDRESS HERE> | echo -a Now Hiding your vHost }
.Unhide:{ mode $me -H | hs on | echo -a No Longer Hiding your vHost }
}
