USAGE
   signed int scdckdel(
           signed int handle,
           void *key,
           signed long recno );

PROTOTYPE IN
   sc_base.h

DESCRIPTION
   scdckdel will remove key from the index file specified by
   handle. recno is used along with key to ensure that the
   proper key has been removed from the index file.

NOTES
   When deleting keys it is not necessary to pad the key string to size with
   spaces (" "), the function will automatically do this for you.

EXAMPLE
   #include <string.h>
   #include <softc.h>
   #include <sc_base.h>

   void main()
   {
     int ntx;
     char date[17];

     scdinit(20,0);
     if (scdcopenx(&ntx, "TOCDATE.NTX", SC_BUFFER) == SC_SUCCESS) {
       strcpy(date,"12/05/8815:30:04");
       scdckdel(ntx,date,7L);
       scdcclose(ntx);
     }
     scdterm();
   }
