GrandFather, thanks for the explanation and suggested fix. I'll take a look and do some reading up on the "print join" thing to work out how it works, then have a play with it in my code once I've sussed it out.

I much prefer the option of avoiding the cause of the warnings, rather than simply suppressing them... never know what you're missing out on in the way of warnings you SHOULD be getting :)
