SUMMARY
In MASM 6.1 there are four new distance specifiers: near16, near32, far16, and far32.

A near pointer consists of an offset. A near16 pointer is a near pointer that consists of a 16 bit offset. A near32 pointer is a near pointer consisting of a 32 bit offset. A far pointer is a pointer that consists of both a segment and an offset. A far16 pointer is a far pointer that consists of a segment and a 16 bit offset. A far32 pointer is a far pointer consisting of a segment and a 32 bit offset. Segments are always 16 bits. Note: near32 and far32 pointers are only available on 386 and successive processors.



MORE INFORMATION
The properties of the new distance specifiers are summarized by the following table:  pointer    size in bits        contain            example ---       -    ---  near16       16 bits           offset_16            IP  near32       32 bits           offset_32            EIP far16       32 bits       segment:offset_16       CS:IP far32       48 bits       segment:offset_32       CS:EIP
