I don't normally read these newsgroups, but this message was brought to my attention. The fact is that somewhere around 5% or 10% of the code in vi is really ed. The buffer management mechanism, the ex command interface, and the file I/O stuff, for example, are pretty much unchanged from ed. For this reason, vi and ex are covered by the AT&T UNIX license, and cannot be considered public domain. Mark Horton
