- This book is a technical reference. It is NOT a tutorial. Hopefully, this
- book is what you'll reach for when you want find out what Peter Norton or the
- "official" references glossed over.
-
- This manual is intended to replace the various (expensive) references needed to
- program for the DOS environment, that stack of magazines threatening to take
- over your work area, and those odd tables and charts you can never find when you
- need them.
-
- The various Microsoft and IBM publications and references don't always have the
- same information. This has caused some consternation about the "undocumented"
- features to be found in DOS. In general, if a call doesn't appear in the IBM
- DOS Technical Reference it is considered "undocumented" although it may be in
- common use.
-
- Microsoft's offical policy toward DOS has been to put the burden of documenting
- and supporting their product to their vendors. Microsoft will not answer any
- questions concerning DOS directly since they don't officially support it. This
- leaves what information IBM and other OEMs (DEC, Zenith, et al) have chosen to
- publish, and the information obtained from programmers who've poked around
- inside it.
-
- Now that Microsoft is selling MSDOS 3.2 and 3.3 as Microsoft products they seem
- to be dragging their feet over whether they will have to support the generic
- version since it doesn't have an OEM name on it anymore. In view of their push
- to OS/2 (OS/2! Just Say No!) further support of DOS seems unlikely.
-
- The information here is valid for DOS 2.x and 3.x. Where there are differences
- between the two versions there are notes in the text. No great effort was
- expended on DOS 1.x or networking features.
-
- As I write this there is still considerable furor over incompatibilities with
- DOS 4.0. Since a Technical Reference for 4.0 isn't availible yet, I don't have
- a whole lot of info on it.
-
- When I started writing this book, it was originally for my own personal use.
- Then I began expanding it with the idea of getting it published, since at that
- time there was *nothing* in print like it. If I had managed to send it off to
- the publishers early enough, I would have had it made. As it was I lost six
- months having a nice steel rod put in my leg, after being run over by a car,
- and half a dozen similar books were published by then, and nobody was
- interested in mine. Six months is a long time in the PC world.
-
- That's why I'm uploading this file as "user-supported." It gives me a chance
- to recoup a few bucks for the year or so I've been working on this thing, and
- it gives some advantages that a printed book can't - first, you can load it on
- your hard disk and use Vern Buerg's LIST or SideKick to scan through text. You
- can grab a peice of something and paste it into a document, etc. If you help
- support the PC Programmer's Reference you will always have the latest version
- availible; you can't "upgrade" books.
-
- A project this size takes a LOT of time and effort. I've tried to verify as
- much of the information I've received as I could, but there's just too much for
- absolute certainty.
-
- If you find any typos, incorrect information, or want to see something else,
- let me know. If you have any more detailed information on something, PLEASE let
- me know!

-
- As is common these days, I have to make a "Notice of Disclaimer". I take no
- responsibility for anything, and if anything you do with this book ruins you
- for life or makes your dog bite you, or anything else, that's just tough.
-
- I hope you find much use for this reference. It was a trip to write, too.

- The information presented here was gathered from megabytes of files found on
- BBS systems, conversations on a dozen different BBS systems, correspondence,
- and every reference book I could get my hands on. On occaision, a number of
- prestigious references didn't agree with each other. Where this has happened, I
- have used the latest references. There is too much information here for me to
- verify every fact personally. I have used my own judgement as to the
- reliability of the sources.
