The SET VERIFY command causes CDO to display all commands in a
    command procedure before executing them. The initial setting is
    off (NOVERIFY).

    To override this default, you can issue the SET VERIFY command
    at the CDO prompt before you process the command procedure. SET
    VERIFY then remains in effect until you issue a SET NOVERIFY
    command.

    Alternatively, you can insert the SET VERIFY command as the first
    command within your command procedure. SET VERIFY then remains in
    effect until the command procedure finishes executing.
