Thanks for the reply. Although I'm sure you wont believe me, I read the rules before I posted.

After posting the question I realised that it wasn't clear. In the example I used above, I was after the last argument (which the thread you suggested does show how to do) but my question was as per the second article. That is to say it could be anywhere within the argument list. If i were to search, the terms I would be using would be position, argument, file, all terms ubiquitous to most threads. That is why i chose against searching.

Thanks for your response.

Mitch.

P.S. I am a nice guy, and understand where you are coming from. I know from experience what it is like partaking in forums where people ask questions that have been asked a hundred times before. I didn't just ignore the search feature off the cuff. Sorry if I pi**ed you off.
