Hi Dan,
Thanks for the info, I should have thought of that simple work-thru; and thanks for spotting the dot error, I thought that looked strange but it was late and I was tired.
I might add that there are many electronic addresses in this publication but not all are underlined and there is no hyper-link text. I take these as enhancements to call the sighted reader's attention to them. If I find any hyper-links I'll retain the underlining for distinction and make an entry on the TN page.
Fred
