Hi Martin, Thanks for your reply, I actually started trying to do this with popen, but didn't pursue it as I wasn't sure that it would work this way. Now that you have confirmed that it can be done like this, I will continue on this path (and will read up on subprocess etc as well :-)). Thinking about it my question would have probably sat better in a python forum, but I got the answer/direction I needed so no regrets.
