This topic provides short examples of using CDO command
    procedures. You can include any CDO commands that you can use
    interactively (including the CDO DEFINE command) in a CDO command
    procedure and execute it at the CDO prompt using the at sign (@).
    See the CDO @_At_Sign command description for more information.

                                   NOTE

       You cannot execute the CDO EDIT command in batch mode.

    The following CDO command procedure, START.CDO, places you in
    the [BOB.DICT] directory, then lists the definitions in that
    directory. The first CDO command, SET VERIFY, instructs CDO to
    display each subsequent command on the terminal screen before
    execution.

    SET VERIFY                        ! Echoes each command executed in this
                                      ! procedure at the terminal

    SET DEFAULT USER$DISK:[BOB.DICT]  ! Places you in the [BOB.DICT]
                                      ! directory

    DIRECTORY                         ! Lists the definitions in the [BOB.DICT]
                                      ! directory

    To execute a CDO command procedure with a default file type of
    .CDO, you do not need to specify file type. The following example
    shows the output of the previous START.CDO command procedure:

    CDO> @START

    SET DEFAULT USER$DISK:[BOB.DICT]

    DIRECTORY

    Directory USER$DISK:[BOB.DICT]

     CDDPLUS                                          DIRECTORY

    CDO>

    If you do not use the default file type of .CDO for a CDO
    command procedure, you must specify the file type to execute the
    command procedure. In the following example, the CDO AT_SIGN (@)
    command executes the CDO commands in the CHANGE.PROCEDURE command
    procedure:

    CDO> @CHANGE.PROCEDURE

    In the following example, the CDO$INIT.CDO initialization file
    sets your default repository directory. Oracle CDD/Repository
    automatically executes the initialization file when you invoke
    CDO from the OpenVMS directory that contains it.

    SET VERIFY                         !Echoes each command executed in this
                                       !procedure at the terminal

    SET DEFAULT USER$DISK:[JOHN.DICT]  !Places you in the [JOHN.DICT]
                                       !directory

    DIRECTORY                          !Lists the dictionary definitions
                                       !in the [JOHN.DICT] directory

    The CDO$INIT.CDO file produces the following output:

    SET DEFAULT USER$DISK:[JOHN.DICT]

    DIRECTORY

    Directory USER$DISK:[JOHN.DICT]

     BACK_ORDERS;1                                FIELD

     CDDPLUS                                      DIRECTORY

     ORDER_NUMBER;1                               FIELD
