What would you think about maybe killing the %z = line and add on on load and menu option that uses a goto loop to add channels to the %z variable

for instance

on *:load:{ setchannels }
alias setchannels {
  if ($input(Would you like to add a channel?,y,Add a channel) == $true) {
    :addanother
    var %tmptmp = #$$?=\"Enter the channel name to be added.\"
    if (%tmptmp != $null) && ($istok(%z,%tmptmp,32) != $true) {
      %z = $addtok(%z,%tmptmp,32) 
    }
    if ($input(Would you like to add another channel?,y,Add a channel) == $true) { goto addanother }
  }
}

This seems sloppy to me but i tried a while ($input() != $true) line and it wouldnt work for me.

Honestly tho Im just trying to convey my idea, not make the best code I can.

Anyhoo then you could maybe even add a..

menu channel,query,status,nicklist { Set $chr(36) $+ Broadcast Channels:setchannels }

It did occur to me that you might also want to include a removechannels alias but making that from the example above would be pretty easy and im only trying to convey an idea here.
