Hi Joerg,

You may have already noticed the GROWPS and PSINCR registers, which were
recently added to ms, in the CVS.  These provide hooks into .NH, which
will let you achieve this -- the SHEAD macro we discussed previously can
effectively be reduced to

   .nr GROWPS 4
   .nr PSINCR 1p
   .de SHEAD
   .   NH \\$1
   .   nop \&\\$2
   ..

Add to this, whatever you need to set up your page heading string, and
your TOC collection -- the point size adjustment will now be handled
directly within .NH, and you should get the new section number in the
page header, when a section heading appears at the top of a new page.

HTH.

Best regards,
Keith.

P.S. for another approach to adding some layout control to the ms
default TOC, have a look in spdf.tmac -- see the .XN macro -- in the
pdfmark.tmac package I posted last week.
