Is there a C compiler that allows a 386 PC running under DOS to use either
extended memory or expanded memory easily. I wan't to have some fairly
large data arrays?

Phar Lap DOS EXTENDER, which allows running programs in 386 protected mode while still getting DOS function access (as well as being able to capture interrupts). Virtual memory management is available at extra cost. 2). Either Microway's NDP C-386 compiler (tends to be UNIXish) or the Metaware High C 386 compiler (somewhat strange, but generates the best code). If you don't have the bucks, your best bet is to find the bucks as dealing with expanded memory is a real pain. You'll also loose about half the efficiency of the chip running it as a brain-dead 8086. Tom Almy toma@tekgvs.labs.tek.com Standard Disclaimers Apply

I too have been (trying to) keeping track of the companies that provide
use of expanded/extended memory on a 386; I received a few quotes about the
following companies:
1) Microway - (508)746-7341 - 386 native mode compiler under DOS
2) NDP - applications require FP co-processor
3) Metaware High C 386 Compiler - what kind of debuggers are supported?
4) Watcom 386 C compiler - what kind of debuggers are supported?
5) GNU - is there a C run time library available?
6) Zortech C++ - debuggers?
(this newsgroup has hear a LOT about this company)
That's all the information I have been able to find out. What I would like
too know is where to get more information about these companies? I've
looked in several computer mags, ask a few computer store bums, looked in
my glove compartment and have come up with ZIP! NADA! SQUAT! Do these
companies ever advertise or do they just whisper it to someone on the
network and hope it gets spread around? Even though I'm a lowly plebe
programmer, I'd guess a lot of software companies would afford descent bucks
for a 386 compiler in order not to worry about ex[te,pa]nded memory. Having
a development environment where you didn't have to rig your data/program
size would seem to produce more reliable code.
If anyone has any idea where I can find out about the forementioned
companies (addresses, magazines , phone numbers, etc.),
I would greatly appreciate it. The basic information sought includes:
- Use of expanded? use of extended? is it seemless?
- How extensive is their libraries compared to MSC 5.1?
- Which (if any) debuggers can they support?
- What memory models are provided? what about lint?
- What are the features of the current release?
- Are there still major bugs in the compiler (known)?
- How reliable/stable is the company and their tech support?
- How good is there documentation?
- Does the package come with good/acceptable utilities?
(no more editors - there are enough good ones to choose from)
- How much does the package ~cost? (please don't scare me / :-()
If any company has developed any application(s) from any of these
compilers from ground up, I think their input would be quite noteworthy.
If there is sufficient interest/responses, I could produce Ye-Olde-Sumry
in a couple weeks.
