I haven't checked those listings yet, though. I've looked through that archive now. The arithmetic coding seems to all be there. They also offer the sample files for the compression contest. What I'd always found fishy about their offer to send them out on floppy disk was that the files are supposed to be a couple of megabytes each. Sure enough, what they hadn't made clear before is that the files they send you are small samples of the sort of thing you might have to compress. They do NOT apparently send you the actual test data! But just to confuse the issue a bit more, their listing of files they supply doesn't match up with the files they actually supply in this archive! I kind of wish they wouldn't be so haphazard with this sort of thing. -- Kevin Martin sigma@rpi.edu
