Doors might have to be a special object, which you'd point to in the 
first line as a vnum, or put in -1 if it didn't exist.  In other words, 
create an object (give it a num of 1234) which you consider your door.  
It has all the regular keywords of an object, descriptions, and so on.  
Then, instead of indicating that this exit has a door, you give the 
number of the object.

Looking in the specified direction (say, east) would give you the short 
description of the door, if closed, and the short description of the exit 
(as usual) if opened.  You could always get the short description of the 
door by doing a "l at east door" or whatever.

So, as an example, this might be our new door: (note that the door's 
status would be contained as a flag in the object, not the exit)

Looking in this direction you see blah.
1 -1 4321	<- I don't know about this...  it should be scrapped ;p

To shut off the presence of a door, replace 1234 with -1, as usual.  You 
wouldn't need to put in keywords for the exit; the ones for the door 
object would cover that.  The MUD should be bright enough to check those 
automatically when it figures out if the door is closed, locked, etc.

In my continuing efforts to promote English as a viable spoken (and 
written) language, try "go east" or just "east" (assuming the door's
open and there's no others around).  The existence of a door should be 
irrelevant if it's open.
