^^^^^^^^^^^^^^^^
Why are you doing this?
real_room() finds the rnum of a given virtual number, and have nothing to do
with the index of the world array. i is the rnum of the room (as you use
later). So, what you are checking is if there exists a room with the
virtual number of the rooms rnum. Or have I missed something?
As a sidenote it is a somewhat costly function to use for a loop going
through every single room in the MUD, as it in turn would search through the
world each time...

If your world array is sorted as in the standard edition and you want to
do some easy optimizing, you could for example stop searching after you
reach the end of the zone you are checking, and perhaps use binary search
to find the beginning of it.
Or if you trust the correctness of your zonefiles you might use the
zone_table to find the beginning/end of the zone.
Or... ;-)
