  if (%chl.emode == on) { var %m = on | set %chl.emode off }
  if ($me isop %c) { mode %c -l }
  hdel chltbl %c
  if (%m == on) { set %chl.emode on }
  chl.load
}

alias -l chl.load {
  var %x = 1
  did -r chlimit 2
  while ($hget(chltbl,%x).item != $null) {
    var %y = $hget(chltbl,%x).item
    did -a chlimit 2 %y
    inc %x
  }
}

I want to add the user level 2000 comands like !limitchan #chan (ads a chan for setting limit) and !setdif #chan difference (how larger will the limit be).

Thanks wink
