I am looking at a copy of "Software Components with Ada", the book that accompanies the Booch components. Under the topic of "external sorting", it shows the specs for two utilities: natural merge sort and polyphase sort. I believe the book is available separately. Any help? (By the way, I know we're sensitive around here about not capitalizing Ada, but since you were shouting in your "Subject", it probably would have been OK. :-) ***************************************************************** * Chip Bennett, GDE Systems Inc | BennettC@j64.stratcom.af.mil * * USSTRATCOM/J64213 | Voice (402)294-7360 * * 901 SAC Blvd, Suite 2B24 | FAX (402)294-7912 * * Offutt AFB, NE 68113-6600 | Opinions expressed are my own * *****************************************************************
