Basically by coincidence, it is quite similar
to DOS/4GW I think. Although I've never used
it, it seems to support some INT 21H calls.

However, it also exposes the 32-bit executables
to segments. I don't.

Correct.

Certain HX programs, yes. I'm not actually sure
about those other formats you mentioned. It may
be possible to support the 32-bit component of
them. So long as they don't use segments. I don't
want to support segments.

I have focused on providing a C90-compliant
environment, so mostly it depends on whether
the HX programs you are interested in use
the subset of the Win32 API that I implemented
in order to provide C90 when writing PDPCLIB.

This is what I have:

https://sourceforge.net/p/pdos/gitcode/ci/master/tree/readme.txt

But if I haven't documented something, I'm happy
to answer any questions.

Also, I was somewhat wrong about one thing.
Someone else added "paging" to PDOS, to
support multitasking. But I would rather have
a simple V=R address space. I tried #defining
out the paging code, via NOVM, and it semi-works
but eventually hangs. My intention is to debug
that and switch it off. People will need to
recompile to switch it on again.

BFN. Paul.
