just a simple topic changer and viewer dialog...remember the channel topic only holds so many characters so if you cant set the topic properly it is not the scripts fault is just the topic has a limit :D

dialog Topic_Changer {
  title "Evil-Klowns Topic Changer"
  size -1 -1 400 65
  option dbu
  edit $chan($active).topic, 1, 5 10 390 30, multi autovs
  button set, 2, 140 45 40 12, ok
  button cancel, 3, 185 45 40 12, cancel
}

on *:dialog:Topic_Changer:sclick:2:{
  if ($did(topic_changer,1)) {
    var %count 1
    var %topic
    while (%count <= $did(topic_changer,1).lines) {
      var %topic %topic $did(topic_changer,1, [ %count ])
      inc %count
    }
    topic $chan($active) %topic
  }
}
alias tpc { dialog -m Topic_Changer Topic_Changer }
