Actually, you preceded yourself by about twelve hours: last night I obtained your bibliography from netlib and used it to track down Ward and Gray's algorithm in ACM-TOMS. Apparently, the ACM doesn't distribute these old algorithms anymore, so I had to perform a journal-to-ASCII conversion with our OCR scanner (and edit and debug for a few hours). So, I have this program now, it works great, and I will provide it to anyone else who wants it (I think(?) this is okay by ACM rules). Steven Smith
