Few people?
I thought Oscar was a singular person, not a group of people :-)
Seriously, I am convinced by that approach (thanks) and I wish to go that way, but the problem I am getting now is that the open fails and then I can't go on.

Also, I am now looking at the subprocess as os.popen seems deprecated.
Any opinion on that?
Thanks for your suggestion.
