snake, type /debug on, perform the commands that would display those lines, then look for a file in the mirc directories called debug.log and look in there once you're done, turn off the debug log by typing /debug off
Remember too that a list of raw numerics is usually just the RFC compatible raws. Many (probably most) IRCd's also have their own extra numerics which you will have to find out yourself with /debug as you go along.
