This screen shows all the logicals currently accessible to the
    Performance Monitor, the name of the table in which they were
    defined, and the associated logical value.

    The displayed logical names are listed in suffix alphabetical
    order for quick review. That is, the logical names are sorted
    after removing the facility name (such as RDMS$, RDM$, SQL$).
    This method of sorting is very useful, because in most cases the
    facility name prefix is not known.

    The Defined Logicals screen has two modes: brief or full. The
    brief display mode is the default. You select brief mode by
    typing B (displayed as Brief on the horizontal menu). When the
    Defined Logicals screen is in brief mode, only those logicals
    actually defined and accessible appear. The displayed table name
    is the actual table where the logical resides, and the definition
    is the logical's defined value. The screen is dynamically updated
    as new logicals are defined on the system.

    You select the full display mode by typing F (displayed as Full
    on the horizontal menu). When the Defined Logicals screen is
    in full mode, all known logicals are displayed, whether the
    logical is defined or not. If the displayed logical is defined,
    the table name and logical value are displayed as if the display
    were in brief mode. If the logical is not defined, the table name
    contains the name of the table where the logical should reside;
    no definition is displayed. The full mode is useful for checking
    the spelling of logical names and ensuring the logical is defined
    in the proper table.

    When more than one page of the Defined Logicals screen is output,
    you view the succeeding pages of the Defined Logicals screen by
    pressing the right angle bracket (>) key, as indicated by the
    >Next_page option in the horizontal menu. Then, to move back to
    previous Defined Logicals display pages, press the left angle
    bracket (<) key, as indicated by the <Prev_page option in the
    horizontal menu.

    This screen shows the list of all logicals currently accessible
    to the Performance Monitor; the screen is unable to show logicals
    defined in another process' tables.

    The Defined Logicals screen shows the values of logicals; it does
    not allow you to modify the values of the logicals.

    The output from the Defined Logicals screen is not written to the
    output file; therefore, the output cannot be replayed using an
    input file.

    Due to screen width limitations, only the first 28 characters of
    the logical name are displayed.

    If you are using a multiversion product, the logicals displayed
    do not contain the numerical suffix. For example, if the
    multiversion variant of Oracle Rdb Version 6.1 is being used, the
    61 suffix does not appear for any of the logicals in the Defined
    Logicals screen.
