DislikedFUN - I found the attached indicator on the web. Could you look at it and see if it is correct? I think many of us would prefer an indicator to doing things manually.
An interesting method - I've put Nison's book on hold at the library and am anxious to learn more.Ignored
Compare the indicator with the one in post#8, if it is the same he said it is no good, why I do not know.
I hope this one would be workable.
