All modern VC versions are now full 32 bit, and have been for quite a
while.  I quit working with segmented memory models almost three, maybe
four years ago. (which is 28 years in PC years <G>)

I don't think you can get a 16 bit pointer any more.

In addition, under Win32 all memory is a virtual memory address space
thing, where all code lives in it's own address space, although I think
there are some differences between Win95 and WinNT with respect where the
OS mapped DLL's live.  So you have to be careful passing memory references
around processes; COM has routines to take care of that (as well as RPC's
and DCOM) and the subsequent marshaling issues.

That's why I mentioned the packing and the INT64 macro's a while ago --
they can help some with this.
