That's definitely *not* silly but the way to go. There are two ways: The above that calls the executable with the arguments as given, or with a string like you suggests which is interpreted by a shell, so the arguments must be escaped for that shell. Which shell?

That fails (unless you really have a program with that name. ;-) Ciao, Marc 'BlackJack' Rintsch -- http://mail.python.org/mailman/listinfo/python-list
