Hello

I apologize if this is a simple request, but all the nroff/troff
people I know don't seem to have any ideas either, so here goes.

I have a very large document, consisting of multiple chapters, and
I would like to pass the ending page from the previous chapter to 
thefirst page of the next chapter (plus 1, of course).

Does anyone have any nifty algorithms for doing this? So far I haven't
been able to figure out a simple way of doing this. 

The only thing that seems doable so far is to append a ".so" to the end
of each chapter, but this is rather unacceptable, as each chapter can
stand on its own, or in conjunction with all others.

The Nroff/Troff Users guide mentions that number registers (.nr %) can
be read or written, but I have seen no example.  Ideally, I would like to
set an environment variable with the page #, so that from a makefile I can
do something like

      "nroff -ms -n$page chapterx.ms"

Any help would be very welcome.

Thank you all
