Dear IV Users,
	In my Unidraw application, I have a toplevel editor which has 4 editors inside it. I can basically switch between editors. Each editor represents a Design Phase in my Application. 

My Question is :

1. How do I make sure that I save the whole application design which is spread over the four editors Whenever I press a Save Option in one of the editors. What additional code is required ?

2. How do I load the design back into the four editors when I restart my session after some time. 


Any help will be appreciated.  

Also How can I clear a Viewer area of an Editor in which I have drawn some graphic. Is there any command available to do that. 


Finally does my Save option need to be one derived from the Unidraw Command Hierarchy. Can It be some PushButton defined by me to perfomr some save operation on being pressed. If so could you give me some hint as to how I can possibly do the save 
operation.





Thanks very much

Sriram
