Hello John,
I was afraid you were going to ask me that!  The file is "Datacomp.exe".  You
copy it to the directory where the TB's are located.  Then type this line:

For %f IN (*.emd) DO datacomp t %f >> t.txt

Then check the "t.txt" file for errors.  I remember there was originally a
problem with case sensitivity in the *.emd files.  I don't remember how it was
resolved. I got all of this from Eugene Nalimov.  He seems to be a very nice guy
and very helpful.

I don't know where to get the file now.  Maybe Mr. Nalimov will give it to you.
I thought it was on Bob' site but I just checked and did not see it.
Jim
