Subject: 3. How To Get The Patch For MASM 6.11

There is a patch available from Microsoft for MASM 6.11.  This patch
converts MASM 6.11 or 6.11a into the latest version MASM 6.11d.  This patch
will not work on MASM 6.11c.

To obtain this patch:

    ftp://ftp.microsoft.com/softlib/mslfiles/ML611D.EXE

ML611D.EXE is a self-extracting file which when executed will create the
following files:

    ERRMSG.TXT      PATCH.RTP
    H2INC.EXE       PATCH.RTD
    H2INC.ERR       README.TXT
    ML611D.TXT      SUPPORT.TXT
    PATCH.EXE

All the instructions for installing the patch are contained in ML611D.TXT.

Subject: 4. What Is and How to Access the Microsoft Knowledge Base

4.1  WHAT IS THE MICROSOFT KNOWLEDGE BASE

The Microsoft Knowledge Base (KB) is a collection of articles that is
maintained and used by the Microsoft Support personnel to answer customer
questions.  Included in the Knowledge Base are detailed how-to articles,
answers to technical support questions, bug lists, fix lists, and
documentation errors.  This Knowledge Base is available to all on
Microsoft's Internet Node.  An index of all the articles is available in a
file, index.txt.

4.2  HOW TO OBTAIN INDEX.TXT

    ftp://ftp.microsoft.com/developr/masm/kb/index.txt

This index still is available with the last entry dated Aug 96.

4.3  FILE FORMAT OF INDEX.TXT

The format of this file consists of three columns.

    Column One is the file type with the following meanings:
        FIX         - Bug Fix
        DOCERR      - Documentation Error
        INF         - Information
        PRB         - Problem
        BUG         - Bug
    Column Two is the path and file name in the following format: Qxxxyzz
        where   the part,  Qxxx', is Q followed by two or three numbers and
                    represents the first subdirectory under the kb
                    subdirectory,
                the part,  y', is the next subdirectory under Qxxx, and
                The part,  zz', when combined with  .txt' is the filename.

                ****WARNING**** Some of the Qs are uppercase and some are
                lower case.  Unlike DOS, the filenames and directory names
                are case sensitive.

    Column Three is a short description of the file.

4.4  GETTING FILES

You can get all the files from the /developr/masm/kb directory without
navigating this very strange directory structure by using the path in the
get command.  As an example, let's say you want Q106399, a very useful file
if you use Visual C++ (see below).  Using the parsing rules above, you can
use the following get command:

    get q106/3/99.txt

4.5  HOW TO ACCESS THE KNOWLEDGE BASE USING GOPHER

    There no longer is gopher access to microsoft.com

4.6  HOW TO ACCESS USING WWW

Microsoft has removed the MASM option from the their www KB search.

4.7  SOME EXAMPLE FILES FROM THE MICROSOFT KNOWLEDGE BASE

Q86815      Mixed C and MASM with MASM Main Language, No C Run-Time
Q86816      Mixed C and MASM with MASM Main Language, C Run-Time
Q101264     Assembling Code Developed for MASM 5.x with MASM 6.x
Q106399     Using the Visual Workbench with MASM
Q110598     Spontaneous Assembly and MASM 6.11 Errors
Q123729     Accessing Command Line Arguments

    I have found Q106399 particularly helpful since I am really upset that
    Microsoft did not include direct support of MASM from within the Visual
    Workbench.

Subject 8. How To Get The Patchs For MASM 6.12 and 6.13

There are patches available to patch MASM 6.11 to update for support
Pentium Pro and MMX instructions (Version 6.12) and AMD 3D instructions
(Version 6.13).  Numerous bug fixes have been added.  You do not need to
download each, ml613.exe contains everything to upgrade your 6.11, 6.11a or
6.11d.  Again, these patches will not upgrade MASM 6.11c

    ftp://ftp.microsoft.com/softlib/mslfiles/ML612.EXE

Subject 9. MASM Free From Microsoft REVISED

MASM Version 6.11d is available on the Windows 98 Software Development Kit. 
It is part of an 18+ Meg file.  The URL to the file is:

    http://www.microsoft.com/hwdev/ddk/download/win98ddk.exe

I still could not download the file, but thanks to Barry Brey who sent me
the expanded directory listing I have discovered the following.  Also
included is a linker, but I could not find the Programmer's Work Bench nor
CodeView for debugging, so downloading this file will provide only the
assembler and linker without any supporting programs nor documentation.
