The problem has now been solved, but I can think of an explanation for Victor's problem with -sed-, namely that there is no such beast on his machine. 

This would probably be the case if he is running Windows. -sed- is in origin a Unix utility. Various Windows ports exist but they must be deliberately installed to work! (As Steve pointed out, -sed- is _available_ for Windows.) 

An experiment indicates that running the command on Windows through ! results in a empty but existent file2.txt even though no -sed- exists on the user's machine. Evidently the Windows shell is smart enough to initialise a file2.txt but then as sed doesn't exist nothing is put in it.

assume that your commas are not separating the integer from the
non-integer part of the numbers, but instead are indicating
thousands--see Jose's post today.

 I suggest that you use -filefilter- instead of -sed- , Since this is
a Stata command, it will be platform independent, whereas the -sed-
command on your system might have a different syntax than the one on
mine (OS X 10.5.8, bash shell) . (The  "-e" might be an issue; you
could omit it.)  Either one of these two statements should work.

filefilter file1.txt file2.txt, from(",") to("")  //best
filefilter file1.txt file2.txt, from(\044d) to("")

 Monitor what is in file2.txt  either  by opening it up in your text
editor (best), or using -type-.

  I'm not sure what you mean by "highlighting" the data, and I'm not
sure that I consider the do file editor as a good text editor. (I
wouldn't want to use it with a thousand-line file).  Still, while you
are there (or in a good text editor), why not search for and replace
the comma, save out, as Jose and Nick suggested.
