Dijkstra was NOT a co-author of that chapter. A trifle pedantic methinks. I meant that Dijkstra was co-author of the book and, according to the English parsing rules I was taught, in "Ole-Johan Dahl in his chapter", "his" should be bound to Dahl, not Dijkstra. I did not, therefore, suggest that Dijkstra was co-author of chapter 3. Cheers....Ron (another pedant when provoked :-))
