   /* day of week (0 = Sunday) */
   }

   #include <stdio.h>
   #include <dos.h>

   main()
   {
   struct dos_date_t date;
   int oy;

        dos_getdate(&date);
        printf("Date is %02d/%02d/%d (day of week %d)\n"
                  ,date.month,date.day,date.year,date.dayofweek);

        oy = date.year;

        printf("\nDate is %02d/%02d/%d (day of week %d)\n"
                  ,date.month,date.day,date.year,date.dayofweek);

        date.year = oy;
        dos_setdate(&date);
