In article <EIJKHOUT.93Jan5155258@cupid.cs.utk.edu> eijkhout@cupid.cs.utk.edu (me, in other words) writes:

   The best I can come up with right now is the following:
	   \edef\tmp{\noexpand\typeout{\thechapter}}
	   \uppercase\expandafter{\tmp}
   which you hide of course in a macro because it's ugly.

I'm so embarrassed. I forgot to say that you have to define
	\def\thechapter{\roman{chapter}}
that is, lowercase, because this is fully expandable.

Evidence (from interactive run):

*\setcounter{chapter}3
*\def\thechapter{\roman{chapter}}
*\edef\tmp{\noexpand\typeout{\thechapter}}
*\uppercase\expandafter{\tmp}
III

See?
