Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    Alpha Four and Linux

    The question of "Can you run Alpha Four under Linux?" has been asked before
    and never answered AFAIK. The following edited exchange is from Dr. Jerry
    Pournelle's (SF writer and long time BYTE columnist) website
    www.jerrypournelle.com and seems to answer the question.


    Tuesday, September 19, 2000

    Jerry: There must be a few that still use Dos programs and would like to use
    one of the Linux distributions. Question: Can a Dos program, like Word
    Perfect 5.1+, be run under Linux? VM Ware touts their program to allow
    Windows programs to run under Linux -- why not Dos programs ? F0r sure, I
    don't see anyone porting Dos to Linux so it will have to be, I guess, run
    under Linux some other way.
    I trust this isn't an imposition.

    John Little

    No imposition but you force a confession. I don't know, and my Linux boxes
    are not running (or like the NetWinder are too critically important for
    experiments) so it will be a while before I can find out for myself; but I
    bet someone here will tell us in hours. And they did. See below.

    ------------------------------------------------------------------------

    DOS programs can be run under Linux.

    If you buy VMWare, you can run Windows, and you can run DOS programs under
    Windows. You could also make your VMWare virtual machine run DOS programs
    directly.

    However, there is a free DOS system for Linux. It is called "dosemu", but
    despite the name it is more of a virtual machine for DOS.
    http://www.dosemu.org/docs/HOWTO/

    I am using Mandrake Linux 7.1 Deluxe, and when I installed it, I got the
    dosemu system as well. I just fired it up for a test. It seems to run PC
    Write and the DOS version of vim just fine. I haven't tried Word Perfect.

    On my Mandrake computer, dosemu came set up with freedos, so I didn't even
    need to scrounge a copy of DOS for it to run. But the dosemu documentation
    says that DOS versions 2.0 through 7.0 are known to work.
    http://www.freedos.org/

    If your Linux system has dosemu installed, then if you type the command
    "man dos" you should get a manual page for it. If not, you can install it
    yourself.

    ftp://metalab.unc.edu/pub/Linux/system/emulators/dosemu/

    Source code is in this file: dosemu-1.0.1.tgz

    Here is the RPM: dosemu-1.0.1-1.i386.rpm

    If you want the source code version, there is a file called QuickStart
    included that describes how to build and install it. --

    RE: Alpha Four and Linux

    Running Netware on a server and Dr. Dos as the client works fine. Caldera joins dos to a linux box via Netware drivers. I would stay away from virtual machine. When your data base grows large, indexing suffers and becomes slow if you are using emulations like dosemu. For number chrunching, keep it simple and give head room to a database. Similarly, if a word document grows large, and you are in a virtual machine,pagenation becomes painfully slow.
