..though if loading debug file annoys you /debug @debug works too..
the line you more than likely want is..
raw 311:*:{ echo -s - $numeric : $2- }
$numeric telling you the RAW number (311) and $2- because $1 shows your nickname regardless, so display the entire raw line..
If you want to halt lines from being displayed in mIRC:
raw NUMERIC:*:{ haltdef }
