On start

The on START event triggers the first time a script file is ever loaded and also every time after that when when mIRC is run.

on <level>:START:<commands>

You can use this event to execute everything you want to do whenever you start your mIRC (e.g. loading dialogs, connecting to several servers, updating some stats).

Example

on *:START: { 
 echo -s Connecting to QuakeNet
 server irc.quakenet.org:6667
}

This example would make mIRC connect to QuakeNet whenever you start it.
