VMS Help RUNOFF, file, Qualifiers, /BOLD  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /BOLD[=n]
       /NOBOLD

    Positional qualifier.

    Specifies the number of times characters are overstruck in
    a bolding operation. You can specify the number of times
    DSR overprints flagged text by stating a value for n. The
    value n must be 0 or a positive integer and defaults to 1.
    A specification of /BOLD=0 or /NOBOLD disables all boldface
    printing, even if the appropriate flags are recognized and
    enabled.
