 Hi,

       I run this simple test file test.tex :

%&cont-en
\setupoutput[pdftex]
\runMPgraphicstrue
\starttext
\startMPrun
  input graphserieA
\stopMPrun
\externalfigure[mprun.1]
\externalfigure[mprun.2]
%
\startMPrun
  input graphserieB
\stopMPrun
\externalfigure[mprun.1]
\externalfigure[mprun.2]
\stoptext
\end .

  In the logfile, I got the messages :

figures        : figureobject test-mprun.1 is reused
figures        : figureobject test-mprun.2 is reused

 and twice the figures of graphserieA.mp on test.pdf.

 Is there a way to avoid the re-use of test-mprun.1 and test-mprun.2, I mean
a way to overwrite the files test-mprun.1 and test-mprun.2 ?

 Or a way to get different names for each metapost output as, for example,
graphserieA-mprun.1, graphserieA-mprun.2 and graphserieB-mprun.1,
graphserieB-mprun.2 ?
 
 I could also give a different number to each of the figures in all of the
*.mp files, but this solution is not pacticable since I have plenty of
metapost files to process, each of it containing a lot of figures already
numbered with almost the same numbers. Moreover, those numbers can not be
modified because the figures are elsewhere referenced by their number and by
the name of the metapost file.

Thanks,
