You might want to look at Watcom C.  It comes with a Dos extender that
allows you to work in flat memory model and still make dos and bios
calls for i/o.  Also there are a number of such extenders, both
commercial and shareware, that will work with your compiler.  I'm not
sure if you can use them within Windows, but underneath all that VC++
gingerbread is a normal command line compiler;  MSC 8.0.

Watcom's debugger might work with their extender.  I haven't used it so
I'm not sure.

A simpler approach that can be used in a few situations is to find the
file unreal10.zip at some ftp site.  It shows how to set up flat
memory and run dos and dos programs with no problems.  The program
has to load within the 1 meg area because dos is limited to that, but
it has all of memory to play with.  The problem with it is that you
can't run a program that goes into protected mode and you can't have
a memory manager.  Other than that it works just fine.

I hope that helps.

		I was faced with the same thing.  I was developing a software
package for the geophysics department over at Western university.
The seismic data sets that these people were using were just gigantic.
They wanted to be able to wave shape, generate the frequency spectrum
and perform a few manipulations which had to force the data set to be
resident in memory.  I attempted the extended memory trick copying
large chunks of memory back and forth so that I could perform the
calculations that were needed.  As I coded the software under dos I
was essentially developing along side some memory management routines.
Later I found that they had access to a Unix based OS and that memory
resources where not an issue.  Well the development changed so
dramatically.  I found it a pleasure to code under Linux.  I wrote
the code so it could be easily just recompiled for any version of
Solaris.

		I would suggest to just jump to linux and develop there then
to attempt to wrestle with DOS or Windows...

If you want to stick with commercial compilers, then your best bet is
probably to look at Watcom C, as someone else suggested.  If you don't
mind going the shareware route, then you have djgpp.  Its a DOS port of
the GNU C/C++ compilers.  It is very stable, and not overly difficult to
use.  It has a debugger that you can pick up separately.  I'm not sure
how robust the debugger is, I haven't used it.  The documentation is
typical GNU and Unix, cryptic and not overly informative, unless you
already know what your doing.  But over all, its a VERY good compiler
for the money.

If you would like more functionality, power, etc, then I would recommend
you load on Linux.  Its a true 32bit multitasking/multiuser OS.  The
problem is, it takes a lot of space and can be difficult to maintain.  It
requires more care and feeding than your standard MS OS, but it gives
you more power and flexibility.  So basically it all depends on what you
really want to do, and how much time you want to spend doing it.

	Does Linux come with a compiler?  The simple answer is "Yes". GNU 
C, C++ and Objective C ( gcc, g++ ).  To be exact though, "Linux" does not 
come with compilers, it's _only_ a kernel. The various distributions, slackware
for example, come with the compilers and lots of other neat stuff.  I say,
check it out; it is an outstanding and inexpensive operating system.

     GCC comes with any Linux distribution.. gcc-2.7.0 is the most recent
version that's stable.  (2.7.2 is most recent but the info file says it has
bugs on x86 compiling.)  2.6.x and 2.5.8 is also fine.  It is of course
32-bit, and is free 8-).  ANSI C, reasonably close to the recent drafts of
ANSI C++ (and objective-C ability is there too), and with Linux's include
files, almost all BSD stuff will compile, POSIX compliant, a few other
things compatible 8-).
     DJGPP is a compiler that along with some runtime 32-bit DOS extender
provides flat memory for DOS.. I don't know where to get it from though. 
There should be a pointer at ftp.gnu.ai.mit.edu.

If you're doing numerical stuff, I would highly recommend Linux over dos. 
From my person experience, using either C or Maple, Linux is several times
faster, even on a machine with less memory.  There are also a huge number
of mathematical packages that have been ported to linux that can be ftp'd
for nothing (Sorry maple isn't one of them)  Scilab for example (lathough it
seems a little quirky sometimes) is a matlab look alike that works quite well
.

Have fun,

Yes.  It's called DJGPP.  Check http://www.delorie.com/djgpp/.  Be
careful, there are 7 or 8 files you have to download, so read the faq
first.
