   The dir command is part of the command processor rather than an external
executable so has to be run like this on NT:
p=piper.PipedCommand("cmd /c dir")
    or on 95
p=piper.PipedCommand("c:\\command.com /c dir")
   although the current command processor should be found from the
environment variable COMSPEC instead of hard coding it.

   You could run all commands with the additional layer of the command
processor if you want. I didn't in piper as there is a bit of overhead to
doing this.

    Try adding the command processor in here. Is "where" a batch file?
