Thanx to both Mike Lucero, and Louis Swaim, i appreciate both of you taking the time to answer my Question.
it is especially heart warming to be answered by sumone who i hold in high regard as Mr Swaim. who i have cum to realize has translated a book i'm about to buy one written by Yang Chen-Fu.
i will note the differences and try to see the changes as advised.
