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

       /SECTION_NUMBERS (default)
       /NOSECTION_NUMBERS

    Controls whether the DSR Table of Contents utility displays
    section numbers in the table of contents. The /SECTION_NUMBERS
    qualifier displays section numbers for all header levels in the
    table of contents. The /NOSECTION_NUMBERS qualifier suppresses
    the display of section numbers for all header levels.
