The (1) I can live with. The (2) I cannot. Our usual virus/trojan locators can't deal with LZEXE'ed files. (They're compressed, so the usual virus signatures can't be found.) I gladly use the LZEXE utility to compress .EXE files on my own PC for local use. However, I will NOT transfer, accept, or in any way deal with LZEXE'd files through any distribution media (to include my local BBS's and SIMTEL20). I STRONGLY suggest you pull the PKCNVT11.ZIP package. If Phil Katz is distributing programs that way .. shame on him! He oughtta know better. Believe me, the minor convenience of already having an .EXE program compressed via LZEXE is NOT worth the threat and potential of viri! (I used the little utility ISLZEXE to find the LZEXE'd program. One of these days I'll back-engineer LZEXE and figure how to "uncompress" one of these compressed .EXE files back to its original state. Until then .. I'll simply live without them.)

The applications you have .exe files for need a wide range of features in the transport and network level support. >but the real problem is that they claim that one has to reboot one's machine >after one finishes using the Novell network. This may be the way things work, but it's not compatibility. If this software supports a packet driver, as our PC/TCP does, you might try the Clarkson 3C523 driver, and BYU's Netware shell. That will provide you multiplexing capabilities, so that the two packages can run simultaneously. The one disadvantage with that solution is that it relies on unsupported software, but in many situations that it not a problem.

I still love this program, but one question occurs to me reading the update-manual: PKZIP 1.1 includes the option of "authenticity verification" as well as "file encryption". Both options are only available in the US and Canada and are not part of the international version. Concerning file encryption I guess this policy is based on some weird US security law. I cannot understand that, but I see no problem there, I do not want to use file encryption anyway. But I would like to use authenticity verification, because it should help to trace hacked or virus-infected archives, and because my PC is used by several people, this would be a helpful insurance. Is there anybody in the US (or elsewhere) who can explain to me the reason why this helpful option is not available outside North-America?

There are two ways to use SORT. The first, which almost nobody ever uses, is to just type SORT at the DOS prompt. SORT will then wait for you to type in several lines of text to be sorted. When you have entered all of the lines to be sorted, hit Control-Z, and the lines will be redisplayed in sorted order. The usual way to use SORT is with input-output redirection using ">" and "<". Following any DOS command with ">" will cause the text which would normally appear on the screen to instead be routed to the file specified, so that the DOS command "DIR C:\ > FILES.TXT" would cause the directory listing to be put in FILES.TXT instead of appearing on the screen. Like- wise, following any DOS command with "<" will cause the text which would normally need to be typed on the keyboard to instead be read from the file specified, so that the DOS command "DEL A:\*.* < YES.TXT", where the file YES.TXT contains only the letter "Y" and a carriage return, would read the answer to the question "Are you sure?" produced by the DEL command from YES.TXT instead of from the keyboard. As for SORT, the DOS command "SORT < NAMES.TXT > NAMES.NEW" would cause SORT to read the contents of the file NAMES.TXT and create a new file NAMES.NEW which contains the sorted contents of NAMES.TXT. There are also a couple of options for SORT. "SORT /R" causes the sort to be performed in reverse ("Z" to "A") order, and "SORT /+nn" (where "nn" is a number between 1 and 255) will cause the sort to be performed starting with column nn. > I have a couple ascii files which are garbled.

Anyone have any > idea how I can strip the high bit and save the new version of this file? This is another place where output redirection can be used. If the LIST command can display your file cleanly, the command "LIST FILE1 > FILE2" should be able to capture the clean version of FILE1 into FILE2. | Leslie Houk | The opinions expressed herein do | | Office of Academic Computing, A23 | not necessarily reflect those of | | University of Texas Medical Branch | the OAC, UTMB, the State of Texas, | | Galveston, Texas 77550 | etc., etc. | | THEnet: BEACH::LHOUK | Familiarity breeds contempt... and | | BITNET: lhouk@UTMBEACH | children.

The package should be capable of recording the hours worked by employees (in timesheet format) on a client or job basis and ultimately invoicing the client for that time. I realize this could be setup with a database or spreadsheet program, but I would like to avoid re-invented the wheel. I cannot help but to think that this sort of requirements has been met before by some easy-to-use program. Any ideas? Thanks, Dennis Systems Analyst, BCIT, Vancouver, B.C.

Just what I need, more complications... it turns out that the computer crashes where not directly caused by the hdrive. Here the situation...with the entire system set up, I boot from floppy, not accessing the hdrive not nor the COM port in ANY way, things run fine off the floppy. But as soon as I use the hdrive or the COM port, things will die in EXACTLY (right down to the sec.!) 30mins. This crashing will occur independent of the two cards being in. That is, with the hdrive stuff out, crashing will occur if COM is accessed, and like wise for the multi I/O card with the COM port. The parallel access doesn't seem to affect anything (yet). Its probably a faulty DMA controller which get screwed up when certain interrupts are generated. Anyone with suggestions? Thanks in advance.

Anyway, our college just got an IBM Page Scanner (Model 3119) and they are looking for a way to incorporate some graphics that they scanned into this program. They used IBM PageScan as the program to scan the image and editied it with Aldus PageMaker. They want to know if there is anyway they can somehow along the way incorporate this image. Their program, as stated, is written in C, but they are desperate for any method that can display the image on screen, and then go into their program. So far the only idea we can come up with is to use something along the lines of a READMAC, or GIF file viewer. Thanks for your advice and help. -Dan Newcombe KK4D@MARISTB ------------------------------ Date: Mon, 26 Mar 90 15:40:46 -0500 (EST) From: "Thomas James Menner, Jr." <tm11+@andrew.cmu.edu> Subject: PC => DECWriter IV Can a DECWriter IV be wired up to a PC? The printer has a 25-pin male connection which would imply that it's a serial connection, but most PC serial ports are male as well. Do I need to find a female-to-female cable? Is it even a serial connection? (I don't have the documenation on this printer, so I'm hoping someone else has run across this.)
