It is my understanding that standard mode windows does not 
itself provide DPMI services; that's what it says in the 
documentation with C/C++ 7.0, which needs DPMI services and
must be run either in Windows enhanced, or from DOS while
using (something like) 386max instead of emm386 (which also
does not provide DPMI services). The combination of 386max
and Windows standard mode does not provide DPMI either. I am 
running windows 3.1.

Hope this helps,
Dan
