Hi Charles,

(Apologies for calling you Chris in my previous response.)

I tried using your suggestion in various ways, but in each
case it seems that, although cmd.exe is called at some point
and displays its version, etc., it never exits, so that each
time it is called another shell instance is opened.  In the
end I have had to type "exit" several times to exit the DOS
window.  This is Windows 2000 Pro, SP2.

Here's one session as an example (sorry if it wraps in
posting):

End of session clip -------------------------------------

I also tried putting the SET command that you suggested into
a batch file and running that from a CMD.EXE prompt, with
similar results.

TIA for any further advice or assistance.
