define room <character generation>
prefix <the room of >
look <Here you can make selections and roll for attributes that further define your character.>
out <Room 1>
place <Room 1>
end define

the error message then reads: "Missing 'end define' - unable to open file". The interesting thing is that if I take out the word "define" from the
look<Here you can...define you character>
everything works fine. So it appears that one would never be allowed to use that particular word in any text description (though perhaps only relating to look). I suppose that means this problem could happen with words other than define. Could make for difficult to figure out bugs...
Any insights? Am I just being dumb? Seems simple enough...
