(exact year & author unknown to me. Does anyone know? I'd like to go about getting the article). I've been told that the layers.library is the pseudo-code from the paper implemented in C almost verbatium. The person that told me this added that there is room for optimization but since it would be a big ROM change, it wouldn't be in 1.2 or 1.3 (this was a while ago). Did C-A have the time/personpower to optimize the routines? Inquiring minds want to know. -- Drew University -- Tom Limoncelli C M Box 1060 -- limonce@pilot.njin.net limonce@pilot.rutgers.edu P O Box 802 -- tlimonce@drunivac.Bitnet <<<-has a "T" in it.
