/PAGE_NUMBERS=option

    Controls whether the page number references in the index are
    running page numbers or chapter-oriented page numbers. To specify
    the type of page numbers you want, select from the following
    options:

    Option       Purpose

    NORUNNING    Specifies chapter-oriented page numbers (such as 1-
                 3, 10-42). You can specify chapter-oriented numbers
                 for an index even if they do not appear in the
                 document. The NORUNNING option is the default.

    RUNNING      Specifies running page numbers (such as 1, 50, 230).
                 You can specify running page numbers for an index
                 even if the document does not display running page
                 numbers.
