       char    month;      /* month (1-12)          */
       int year;           /* year (1980-2099)      */
       char    dayofweek;  /* day of week (0 = Sunday) */
   }

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

   int 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;
       date.year = 1991;
       dos_setdate(&date);
       dos_getdate(&date);
       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);
       dos_getdate(&date);
       printf("\nDate is %02d/%02d/%d (day of week %d)\n"
