I would like to know the raw number in need to use for my auto identify script.

You don't need a raw number, you just need to put the identify command in the "Perform" section in in the Options dialog or in an on connect event.

but I need to use a raw for the options I am including in the auto identify script

Well there are alot of raw numbers..you can use 2 ways to find out what number it is

1. tells mIRC show all data sent to and from the server in @Debug, when the raw is sent, it will be in there.

2. echoes all raws recieved to the status window, along with the data in them.
