I am one of Roy Stockdill's strongest critics and from the list - and references to him which I found on GOOGLE - I continually get the impression of his being an arrogant, self-satisfied bigot who knows all and does not suffer fools gladly. However, I do acknowledge his attitude in this instance which is another take on the Chinese (?) proverb about Give a man a fish; and you feed him for today. Teach a man to fish; and you feed him for a lifetime Regards Malcolm Bull
