  16.    The best I can come up with right now is the following:
  17.        \edef\tmp{\noexpand\typeout{\thechapter}}
  18.        \uppercase\expandafter{\tmp}
  19.    which you hide of course in a macro because it's ugly.
  20.  
  21. I'm so embarrassed. I forgot to say that you have to define
  22.     \def\thechapter{\roman{chapter}}
  23. that is, lowercase, because this is fully expandable.
  24.  
  25. Evidence (from interactive run):
  26.  
  27. *\setcounter{chapter}3
  28. *\def\thechapter{\roman{chapter}}
  29. *\edef\tmp{\noexpand\typeout{\thechapter}}
  30. *\uppercase\expandafter{\tmp}
