Numerous Oracle RMU command operations accept lists of names
    as values for certain qualifiers, such as the Areas= or Lareas=
    qualifiers. The command syntax can easily exceed the maximum
    length of 1024 characters accepted by DCL. To overcome the
    problem of syntax that is too long, you can include the names
    in an indirect command file and specify the indirect command
    file following the qualifier. Throughout this manual, this is
    commonly referred to as using an indirect file reference. Note
    that indirect command files can be nested to any depth.

    Each indirect command file (default file extension .opt) contains
    a list of names with one name per line. A comment, preceded by
    an exclamation point, can be appended to a name, or it can be
    inserted between lines. A reference to an indirect command file
    in the list must be preceded by an at sign (@)  and enclosed in
    quotation marks (""). For example: "@EMPIDS".

    The following example shows the contents of an indirect command
    file called empids.opt. It lists the EMPIDS_LOW, EMPIDS_MID, and
    EMPIDS_OVER storage areas. The last line in the example shows how
    you would reference the indirect command file in an Oracle RMU
    command line with the required quotation marks.

    $ TYPE EMPIDS.OPT
       EMPIDS_LOW      ! Employee Areas
       EMPIDS_MID
       EMPIDS_OVER

    $ RMU/ANALYZE/AREA="@EMPIDS" MF_PERSONNEL ! ANALYZE EMPLOYEE AREAS
