K 10 svn:author V 3 bde K 8 svn:date V 27 1998-08-13T19:03:22.000000Z K 7 svn:log V 327 Cleaned up previous commit, mainly by moving repetitive calculations of invariants to cyattach(). Fixed minor bugs: - cyparam() returned without restoring the ipl in the error cases. This was harmless because cyparam() is always called at spltty(). - one check for "rev. J or higher" actually checked for precisely rev. J. END
