In respect of Bert Gunter's signature quote: "Data is not information. Information is not knowledge. And knowledge is certainly not wisdom." The other day my wife saw a grocery truck with the following remark emblazoned on its side: "Knowledge is being aware that a tomato is a fruit. Wisdom is refraining from putting tomatoes in a fruit salad." cheers, Rolf Turner -- Technical Editor ANZJS Department of Statistics University of Auckland Phone: +64-9-373-7599 ext. 88276
