I am not a very good C coder and I was wondering if anyone could help me
with the following...
Can anyone see anything wrong with this code?? it worked pretty ok,
until I added the little if(EXIT(ch, dir)) which I thought would check
to make sure it was a valid direction...another problem is if I try to
scan twice in a row...nothing happens..it freezes the mud...doesn't
crash but altogether freezes. Any help!???!?

TO_CHAR);
