Thanks Neil, actually in my original post I was wondering about a=20
technique such as what you describe,  I haven't tried it yet and was =20
curious if others had used it. When I get back to this project in a=20
couple of days I may give it a go along with some of the other awesome=20
suggestions by folks on the list.
Cheers,
Jim
