Examples

   AdgConnection ProdDB = new AdgConnection("*Public/DG NET IBM i");
   char Quit400App = '1';
   string CustName;
   decimal TimeOfDay;

  /* We know that the first two parameters will be for
   * returning values, so we set their DataDirection
   * enumeration types to Output. The third value will
   * be sent in to tell the external program whether or not
   * to quit running, but will not return a value,
   * so we set its DataDirection type to Input. */
