Not all raws are numbered, some have names. Such as PRIVMSG, NOTICE, JOIN etc. If you want to find the prop name of a raw, use /debug @window and watch for it.
For example the raw recieved for an incoming dcc send looks something like this
<- :nick!~ident@host PRIVMSG yournick :DCC SEND filename.ext ip port filesize
You can reference this raw message with $rawmsg if $N does not give you all the information you need.
