[Coco] splitting the screen

[Wayne Campbell]

Iam writing it in Basic09. I know about dwset and owset. I have done a 
little with overlays. I've had problems with getting a device window to 
appear the way I want to, and I'm not sure yet about making sure all user 
input is echoed in one window, and all other data coming in to another.
