Hi Wolfgang,
Thank you very much ; as usual your explanations are always clear and your
approach to the problem intelligent and original. I would however like to
know the way in which we can use the command \frameletter except for the
rounded corners with outlinetext. For example, this doesn't work.

\startMPcode

     draw outlinetext.f
         ("\frameletter{A}")
         (withcolor darkred withpen pencircle scaled 1/10)
          rotated 5 xsized 2cm ;

\stopMPcode

Fabrice
