I had gained interest in the conversation part-way and failed to catch-up on my background reading. I appreciate the enlightenment, and especially appreciate the extra explanation you provided in the post which I'm replying to. I'll make sure that I re-read it and the other posts related to it. I would have done so already, but I'm currently pre-coffee and swamped with end-of-financial-year paperwork. ;( Cheerio, Paul -- Paul Fenwick <pjf@perltraining.com.au> | http://perltraining.com.au/ Director of Training | Ph: +61 3 9354 6001 Perl Training Australia | Fax: +61 3 9354 2681
