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! Terrell
