The PK versions were quite a bit faster, actually, but a lot harder to use, since they have a separate program for compress and uncompress. ARC (and zoo, dwc, and lharc) put it all in one program with one user interface. |> |> For what it's worth, I thought that the basis of the suit was that Henderson |> owned the filename extension '.ARC'.

They had an independent consultant look at both sources, and testify on the matter. Right after that PJ settled out of court and promised not to compete (with any program processing ARC files) again. The testimony was sealed, but I doubt that the expert said the sources were completely different. -- Bill Davidsen (davidsen@crdos1.crd.ge.com, uunet!crdgw1!crdos1!davidsen) GE Corp R&D Center, Schenectady NY Moderator of comp.binaries.ibm.pc and 386users mailing list "Stupidity, like virtue, is it's own reward" -me
