DOSREF v2.0 by Dave Williams Registration $20.00
MISC JUL91 WILLIAMS MSDOS DOS IBM REFERENCE
FILES: dosref20.sdn
New to SDN
From the author of FLEX...
Programmer's
Technical
Reference
for MSDOS
and the IBM PC
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 documented by other OEMs or by later Microsoft tech
bulletins.
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 3.3 and 4.0 over the
counter 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 through 4.x. Where
there are differences between the two versions there are
notes in the text. No great effort was expended on DOS 1.x.
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. (late 1987) 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 drug addict in an uninsured
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.
