You have not said whether your program will be in machine language, C, 
Basic09, or something else. The commands will depend on the language but 
the technique will be the same for all.

Aside from the distinction between graphic and text windows, there are 
two types, a device window and an overlay window. The system commands to 
create them are DWSet and OWSet. These commands can be used directly in 
an ml program or indirectly via Display or DWSET in Basic09.

New windows can have paths opened for read, write, or update. Programs 
running on one window can easily send or receive data from other windows.

This may not be all the information you want, but without a better idea 
of what you want to achieve it is hard to write a demo.
