 main()

       retval;

   char *cat = "sys$disk:[]catgets_example.cat"; /*Force local catalog*/

   char *msgtxt;

   char string[128];

   if ((catalog = catopen(cat, 0)) == (nl_catd) - 1) {
       perror("catopen");
       exit(EXIT_FAILURE);
   }

   msgtxt = catgets(catalog, 1, 1, default_msg);
   printf("%s\n", msgtxt);

   msgtxt = catgets(catalog, 1, 2, default_msg);
   printf("%s\n", msgtxt);

       exit(EXIT_FAILURE);

   delete("catgets_example.cat;") ;  /* Remove the test catalog */
 }

      Running the example program produces the following result:

        First set, first message
        second message - This long message uses a backslash for
                                                  continuation.
        Second set, first message
