My apologies for the delay. I do thank you all for your comments and directions and links. I will answer more fully in a short time. (I'm in the middle of moving to a newer, smaller caravan that my car can tow to my new location in Qld 1900 kilometres from here - so the computer is pretty hard to get at, as well as finding the time. But as soon as this computer is unpacked at the other end - my first priority will be to answer and continue this thread)
Thanks again
