A near pointer points to a location in the current segment.  A far pointer
can refer to an address in another segment.  Consequently, if you cast
a far pointer to a near pointer, the result will be bogus if the far pointer
refered to a different segment.

You can always go the other direction - you can cast near to far, near to
huge, far to huge, etc.  In fact, if you're using windows.h this is happening
implicitly - look at the ansi prototypes for the windows api routines.

And remember - segments are for worms!
