Message-ID: <2618@sun.uucp> Date: Mon, 12-Aug-85 19:19:32 EDT Article-I.D.: sun.2618 Posted: Mon Aug 12 19:19:32 1985 Date-Received: Thu, 15-Aug-85 08:21:56 EDT Distribution: net Organization: Sun Microsystems, Inc. Lines: 26 This statement is both true and false: >System V release 2 has file and record locking. People are getting imprecise about which release and version of System V they're talking about. System V has no record locking. System V release 2 for the VAX has neither paging nor record locking. System V release 2 VAX version 2 has both paging and record locking. System V version numbers are processor-dependent, so features available in VAX version 2 may or may not be available in version 2 for other processors. On the west coast, by analogy with Berkeley releases, these AT&T releases are called System V, V.2, and V.2.2. Inside Bell Labs, they are called sV, sVr2 and [who knows what]. On the net, we ought to employ a consistent numbering scheme. Would somebody who knows more about this than I do please propose one? Remember, it is often years before the general public sees new releases. I have friends who still use Version 7 because it works better than the System III updates their vendors supplied. Microsoft just started shipping System V (not V.2) last month. Last I knew, a few months back, Unisoft was shipping System V, and working on V.2. Bill Tuthill
