                      7: *      Defines the structs and unions used for the direct DOS interface
                      8: *      routines; includes macros to access the segment and offset
                      9: *      values of far pointers, so that they may be used by the routines; and
                     10: *      provides function prototypes for direct DOS interface functions.
