Does anyone have any information on programs such as Polytron PVCS software or any software of this type from any other vendors. Any infomation would help. Bob Lay Kong Shearson Lehman Brothers Branch Automation Systems

I have been using a couple of Polytron development tools, and am generally pleased with their products. Brief review: PVCS (Polytron Version Control System) - it ain't SCCS, but it works. Actually, it seems a philosophical child (or at least nephew) of SCCS. My major complaint is that I haven't figured out how to use the locking options to avoid the "last submitter wins" kind of disasters that befall multi-developer projects. (But then, we are using multiple copies of the older single-user PVCS to access shared source files over a LAN. I understand the newer PVCS comes in a networked version that deals with this problem directly. Also, I haven't worked hard on this problem 'cause it's not a problem in my [so far very small] project.) I'm also impressed with its speed. Several years ago, I used SCCS much more than now; even controlled the drafts of my memos. But I stopped because gets and deltas took too long. PVCS is so fast, you hardly notice. PolyMake - yet another MSDOS-based-almost-UNIX-compatible MAKE program. Actually, it's the best I've used, though NDMAKE (shareware from Don Kneller) and Turbo Make (included "free" in Turbo C from Borland) are real close in most features. (By the way, DON'T use Microsoft's MAKE; it's a toy, not a tool.) The big win for PolyMake is that it works with PVCS. In particular, it knows how to read PVCS archives to get ages of source, knows how to read the revision and version numbers, and can be "programmed" to make certain versions (not quite as convenient as s-lists in sccs, but not bad at all). I'm not connected with any of the companies mentioned above. The opinions expressed here are my own; I don't pretend to speak for AT&T. +---------------------------------------------------------------+ | Dave Tutelman | | Physical - AT&T - Lincroft, NJ | | Logical - ...ihnp4!mtuxo!mtunb!dmt | | Audible - (201) 576 2442 | +---------------------------------------------------------------+

It works very well, except if you use it's file locking procedures with two source files that have the same base name. e.g. graphics.h graphics.c When you check out graphics.h with locking, TLIB creates a graphics.lok file. Then, if you try to check out graphics.c with locking TLIB thinks it is already check out. There was a review a few months back in PC Tech Journal, they picked Polyron PVCS, $300 or so, and TLIB 3.x, $100, as the best. -- Chane Cullens chane@mntgfx.MENTOR.COM

I think SCCS stores the full text of the first version of the document, and then stores deltas so that later versions can be recreated. However, it seems that the most common operation is to check out the newest version, not the oldest. RCS does the opposite -- it stores the full text of the most recent version and reverse deltas so that older versions can be recreated. (Some SCCS-type systems store the full text of the oldest and the newest, just to avoid this problem.) On a system like MS-DOS, where the speed of the computer and/or disks may be a limitation, the RCS approach clearly makes the most of what you have. -- Gerry Wheeler Phone: (519)884-2251 Mortice Kern Systems Inc.
