Example 1 Use an indirect command file to execute a frequently used query: $ TY EMPADDR.RDO ! ! This command file generates information for a mailing list. ! INVOKE DATABASE FILENAME 'DISK2:[DEPT32]MF_PERSONNEL.RDB' SET OUTPUT 'DISK2:[DEPT32]MAILLIST.DOC' FOR E IN EMPLOYEES PRINT E.FIRST_NAME, E.MIDDLE_INITIAL, E.LAST_NAME, E.ADDRESS_DATA_1, E.ADDRESS_DATA_2, E.CITY, E.STATE, E.POSTAL_CODE END_FOR $ RDO:== $RDO $ RDO RDO> @EMPADDR Example 2 You can use a logical name to run a command file: $ SET DEFAULT DISK1:[FORESTER] $ DEFINE COUNT "DISK2:[DEPT3]COUNT.RDO" $ TYPE DISK2:[DEPT3]COUNT.RDO ! ! This command file counts the records in ! each relation in the MF_PERSONNEL database. !
