USAGE
   signed int sccds2i(
           signed int *year,
           signed int *month,
           signed int *day,
           signed char *string,
           signed int format );

PROTOTYPE IN
   sc_clock.h

DESCRIPTION
   sccds2i converts dates from an ASCIIZ string string of the style
   format to three integer values (year, month, and day). A
   partial check is made to verify that string is a valid date string
   before attempting to convert.

   Date string styles:
   SC_GREGOR     mm/dd/yy
   SC_GREGORL    mm/dd/yyyy
   SC_JULIAN     yyyy/ddd
   SC_YMD        yyyymmdd
   SC_DMY        ddmmyy

EXAMPLE
   #include <stdio.h>
   #include <softc.h>
   #include <sc_clock.h>

   void main()
   {
     signed int y, m, d;

     sccds2i(&y,&m,&d,"19890213",SC_YMD);
     printf("%d %d %d",y,m,d);
   }
