The expression ``uppercase number'' makes no sense.

     DO YOU MEAN ``superscript''?

     If so, say so.  I.e. use the correct terminology or no-one can help 
you.

Anyway the command works for me.  I.e. it gives me the "2" as a 
***superscript***.

If you indeed want a superscript, then you must be doing something 
strange, or there is
something strange about your setup.

Can you tell/show me *exactly* what you did?

If you don't want a superscript please make it clear what you *do* want.
As I said "uppercase number" makes no sense at all.

     cheers,
