The DPMI version does do "translations" when it does DPMI simulated DOS calls,
but otherwise it is fairly "sane".  I didn't do that one though, and I'm not
sure I still totally understand it.  The mode switching when it loads
(protected to real to protected) is too much for what I'm after.  Stephen was
aware of the 32-bit app bit from one of your articles (BTW) and the system
runs pretty good.

However, I'm trying to do it all without DPMI, using just windows calls, and I
think I'm getting closer.  Today, I was actaully able to let Windows "free"
from the shackles I have it in.  My first (working)
PeekGetTranslateDispatchMessage loop ran (!YEA!).  I'm finally into the Forth
edit/debug cycle instead of the MASM/MAKE one I've been spending most of my
time in.  I still crash, but I'm starting to even understand why.

I'm using the WINMEM32.DLL stuff that comes with the SDK.  Do you know
anything about it?  I suspect I may have found a bug in it (or insufficient
documentation) when it comes to what GetMessage can use.  I managed to get
around the problem by moving the message in and out of a GlobalAlloc structure
because it didn't like the Global16PointerAlloc that I had been trying to use.
So, now I can use either method.

However, I also found out that Microsoft has no one to answer questions unless
you subscribe to Microsoft Online.  I'm not ready to do that yet.  Do you
subscribe to it, or are you one of the ones who answers the questions?  Do you
know anywhere else that I can find answers to the "really tough" problems?

We should talk!   DaR

BTW, for those "watching" these birth pains, the call that I was trying to
make a few messages ago is compiled by MASM using the following:

        CALL dword ptr Routines[BX]

Almost even makes sense: :)
