/sys$common/syshlp/helplib.hlb RUNOFF, file, Qualifiers, /INTERMEDIATE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /INTERMEDIATE[=filespec]
       /NOINTERMEDIATE (default)

    Positional qualifier.

    Controls whether DSR generates an intermediate output file that
    can be used as input to the DSR table of contents utility and the
    DSR indexing utility. For more information on producing tables of
    contents and indexes, see the descriptions of the /CONTENTS and
    /INDEX qualifiers.

    If you specify the /INTERMEDIATE qualifier, DSR creates an
    output file that has the same file name as the input file and
    a file type of .BRN. To rename the output file, supply a file
    specification that is different from the default values.
