Define

The Define() step is where specific data definitions are established by your application and/or process. This involves defining columns/fields and creating the tables/files with optional indices.

Below is the code for Define():

#ifdef PROTOTYPE

VOID Define(VOID)

#else

VOID Define()

#endif

{

   printf("DEFINE\n");

   /* open files */

   printf("\tOpen table...\n");

   custmast_filno = OpenFileWithResource(-1, "custmast.dat", 0);

   if (custmast_filno < 0)

   {

      /* create files */

      printf("\tCreate table...\n");

      if (CreateIFile(&custmast_ifil))

         Handle_Error("Define(): CreateIFile()", 0);

      /* store record information into data file */

      if (PutDODA(custmast_ifil.tfilno, custmast_doda, (UCOUNT)NBR_OF_FIELDS))

         Handle_Error("Define(): PutDODA()", 0);

      /* close files */

      CloseIFile(&custmast_ifil);

      /* open files */

      custmast_filno = OpenFileWithResource(-1, "custmast.dat", 0);

      if (custmast_filno < 0)

         Handle_Error("Define(): OpenFileWithResource()", 0);

   }

}
