Greetings: I have developed a very pretty and efficient algorithm for threading binary trees, utilizing two pushdown stacks, that is non-recursive, O(n), and i think too beautiful to go unimplemented. (like woman was before god in adam's time.) if you collectors of nifty algorithms and curious implementations people will only ask, i will send it/her thither to you for your inspection and esteemed comment. (it pains me to consign it forever to dwell alone in my dusty notebook (like sending a bright daughter off to a parochial school...) ) (steve m serocki) sdcsvax;sdccsu3;ix222
