                       passed as input
   Parameters - DataSelector:W, CodeSelector:PW

   @DosSubAlloc - Allocates memory from within a segment that was previously
                  allocated and initialized with DosSubSet
   Parameters - SegSelector:W, BlockOffset:PW, Size:W

   @DosSubFree - Frees memory previously allocated with DosSubAlloc
   Parameters - SegSelector:W, BlockOffset:W, Size:W

   @DosSubSet - Initializes a segment for suballocation, or changes the size
                of a previous suballocation
   Parameters - SegSelector:W, BlockOffset:W, Size:W
