Thanks Colin, well hopefully you have had a chance to scroll through the
various programs that have been posted on the site, I would be rehashing
quite a bit to write a program for you, the work I have written for
sexyopenside would be most applicable for you as well, if you check that
one out and get back to me after you have read that and see if you
feel it is useful, maybe Steve Thompson can re-direct you to that or
actually send you a PDF of that article, cheers, ashley
