1  CDO_Command_Procedures
   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.
 

2  Examples
   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
