The captioned reference, from the User Guide, appears clear enough and works well in the "Section" environment but the option is, as far as I can see, not available in the "Section*" environment.
Not sure of the rationale for this decision. My problem is typesetting an old-fashioned book where, for the their pains, the authors- translators have chosen to head each separate article along the lines of "Article XXIV - The old system of wars of position and the modern system of marches" and the Roman numerals run sequentially (regardless of chapter) through the book. Can I force the "opt" box into the "Section*" environment or should I try to work out how to number (Roman) the "Section*" environments independently of the Chapters? I have been unable to locate any obvious reference to either approach (or to think of another). I would be grateful for any hints for this little glitch ---I am reluctant to lose the slightly antique flavour of the book by tampering too much with the style adopted. -- Bruce Weller
