if you want to invite all the nick of the list you should do something like:
Code:
alias invitenick {
   var %count 1
   while ($gettok(%invitelist,%count,%tokchar)) {
    invite $ifmatch #yourchannel
    inc %count
  }
}


where %tokchar is the ascii of the char that you choose, for example if the %invitelist is nick1,nick2,nick3 you should use
$gettok(%invitelist,%count,44)
i didn't try the code, see if it works
