1    /DATABASE

       /DATABASE
       /DIRECTORY_TREE

    Controls whether the information presented is gathered from the
    queue cache database, /DATABASE, or by looking at the actual
    directory tree containing the channel queues, /DIRECTORY_TREE.

    When neither /DATABASE or /DIRECTORY_TREE is specified, then the
    "view" selected with the VIEW command will be used. If no VIEW
    command has been issued, then /DIRECTORY_TREE is assumed.

2    /DIRECTORY_TREE

    See /DATABASE

3    /ENVELOPE

    Display envelope To: and From: for the held messages listed.

4    /FILE_INFO

       /FILE_INFO
       /NOFILE_INFO (default)

    By default, message file size and creation date information is
    gathered. However, this requires accessing each message file.
    Specify /NOFILE_INFO if you want to avoid that overhead.

5    /HELD

       /HELD (default)
       /NOHELD

    Show information only for those channels with held messages.
