btex and etex

[Peter.Andree@t-online.de]

Hi to all,
I have an unsolved problem using the ways Hans
indicated in his book METAFUN. I would like to use the command
        texexec --mptex myfile.mp
because of the commands btex $ .... $ etex in the label-part.
Unfortunately I get all the time the message:

This is MetaPost, Version 0.641 (MiKTeX 1.20e (Snapshot build
187)) (preloaded mem=plain 2000.9.18)  24 SEP 2000 22:55
**D:\ModernArt\test-file.mp (D:\ModernArt\test-file.mp
>> D:\ModernArt\test-file.mp
>> D:\ModernArt\test-file.mpx
! Unable to make mpx file. l.3   dotlabel (btex
                     $\frac{x}{y}$ etex,(50,50));
The two files given above are one of your source files and an
auxiliary file I need to read to find out what your btex..etex
blocks mean. If you don't know why I had trouble, try running it
manually through MPtoTeX, TeX, and DVItoMP

I can't find the reason. The attempt to try it with TeX failed.
I'm running WIN 2000, 128 MB RAM, MiKTeX (LaTeX 1999) and
ConTeXt (Ver. 29.05.2000).

Thanks for help, regards Peter.
