Hello ...from Victor L. Miller

I have been using the Allegro graphics library with the DJGPP for over a year and
it is excellent...... I find the bitmap rotation and palette / true color modes excellent....
I have made some larger scientific visualization programs with Allegro / DJGPP

Now,  the company I work for has switched to WindowsNT and the first thing I realized is that WindowsNT does NOT run DPMI (Protected Mode) programs or what I think of as 32-bit DOS Extended programs that do their own 32-bit memory addressing.
Now,  what I discovered is that WindowsNT runs "standard" 16-bit executables (exe's) fine but it won't run 32-bit DOS applications (which is what DJGPP C programs are of course).  Now I have also confirmed that it is nothing unique to Allegro /  DJGPP but no 32-bit DOS programs run.
I believe that Microsoft has determined in their own minds that 32-bit DOS programs are to blame for Windows being "unstable" and therefore they convinced themselves that the future NT operating system line will not support 32-bit DOS programs.
Now,  I would like your thoughts / confirmation of what I am saying and what have people done to create and run 32-bit DOS programs on WindowsNT.
Does Allegro / DJGPP (and I am also using RHIDE environment) have NT versions, etc ?  What about RHIDE ?  I am thinking that even if Allegro / DJGPP could run in NT I would lose my RHIDE environment (which does not run in NT as well).
Has anyone come up with something that you can put on your NT system which will allow 32-bit DOS programs to run in NT ?
I am concerned because even though Win98 still runs / supports 32-bit DOS stuff I think that eventually windows will be Windows 2000 (Windows Millenium is just a bloated version of Win 98) which is really WindowsNT under the hood, and does that signal the end of 32-bit DOS forever ?

I would appreciated your expert comments ,advice, and knowledge related to this subject.

Many Thanks,
Victor L. Miller
