Hi Les,
I am sorry for not trying your program.
I tried to download it from the site Dann
mentioned but at that moment it was so
busy that I did not succeed to get access
to it, so I gave up.
In the meantime I wrote a rather simple program
myself, which does precisely what I want,
but I possibly could have saved this work
by using your program.
Thanks for letting me know.
