Thanks for the response.

This is gem code so really needs to work with older versions of ruby.
Also something I maybe should have said to begin with (was trying not
to overcomplicate the issue) is that I'm needing to capture the stdin,
stdout and stderr.

I first tried using win32-open3's Open3.popen but had issues trying to
kill the process when I was done with it so then moved onto  win32/
process. I'm now looking at the systemu gem in the hope it will work
without problem.

With Open4 I make the following call on my mac with no issues.

@pid, @w, @r, @e = open4.popen4("perl C:/bin/filepp-1.8.0/filepp.pl -
c")

Does anyone know how I can do this same thing with systemu, assigning
the stdin, stdout and stderr to variables?

Oh and system(cmd) does work but I need to be able to kill the process
once I'm done r/w from its associated streams.

Appreciate any help.
