He wrote what eventually became Hummingbird's TN3270 product, and I remember, probably in the late 1980s, discussing some details of DFT that he had reverse engineered. http://reporter-archive.mcgill.ca/Rep/r2909/humming.html Wikipedia says that Hummingbird is now a subsidiary of OpenText, but I have no idea if Pierre is still there or if they still sell 3270 solutions of any kind.I haven't seen him for many years.
