Hi Hans,
Thank you for your reply. Here is the modified test.tex file following your
indications :
\starttext
\def\MPrunfile#1{\bufferprefix \MyMpRunFile.#1}
\def\MyMpRunFile{graphserieA}
\startMPrun
input graphserieA
\stopMPrun
\externalfigure[\MyMpRunFile.1]
\externalfigure[\MyMpRunFile.2]
%
\def\MyMpRunFile{graphserieB}
\startMPrun
input graphserieB
\stopMPrun
\externalfigure[\MyMpRunFile.1]
\externalfigure[\MyMpRunFile.2]
\stoptext
\end .
The test.pdf output now show four gray boxes with the following messages in
their center
"
name: dummy
file: graphserieA.1
state: unknown
"
(with graphserieA.2 in the 2nd box, graphserieB.1 in the 3rd, etc.)
The test.log file tell
"
\openout5 = `test-mprun.mp'.
system(mpost -progname=mpost -mem=metafun test-mprun)...executed.
figures : figure graphserieA can not be found
figures : figure graphserieA can not be found
\openout5 = `test-mprun.mp'.
system(mpost -progname=mpost -mem=metafun test-mprun)...executed.
figures : figure graphserieB can not be found
figures : figure graphserieB can not be found
"
The figures are not found because a file named "test-mprun.mp" is still
created and metapost's output are still named "test-mprun.*" instead of
"\MyMpRunFile.*". Obviously, \externalfigure can not found any
"\MyMpRunFile.*" files.
If I use \externalfigure[mprun.*] instead of
\externalfigure[\MyMpRunFile.*], then the first metapost's output files
"test-mprun.1" and "test-mprun.2" are still re-used -?by \externalfigure?-
after the second \startMPrun .. \stopMPrun call. (A -?simple?- way to avoid
this systematic re-use of metapost's output would be, in my opinion, the
best of all solutions).
In the present case, I think the problem could be resolved if the
"*-mprun.mp" files were labeled with the prefix name of the metapost file
instead of the "jobname". Thus, for instance, we may read in the log file
after the first \startMPrun .. \stopMPrun call
\openout5 = `graphserieA-mprun.mp'.
system(mpost -progname=mpost -mem=metafun graphserieA-mprun)...executed.
and after the second \startMPrun .. \stopMPrun call
\openout5 = `graphserieB-mprun.mp'.
system(mpost -progname=mpost -mem=metafun graphserieB-mprun)...executed.
Afterwards, metapost's output files named "graphserieA-mprun.1",
"graphserieA-mprun.2", "graphserieB-mprun.1" and "graphserieB-mprun.2" would
be created and then normally found by \externalfigure.
Thanks again,
