Thanks, there's a lack of documentation so the purpose of the example is 
to try to determine this kind of information.

In an emulator the peek and poke routines will be inlined into the 
dynamically generated code. I'm essentially after a multi-segment model. 
I want CS/DS/ES to be in the same flat address space. This means the 
generated code and any spill/fill of register value code will be in the 
controlling address space, I want to then address the second address 
space/segment by just using a segment over-ride.

Thanks for the help,
