VWPORTS (Viewports) allows you to set and manipulate the
number of viewports on the screen. Displaying multiple
viewports is useful when designing a three-dimensional 
part so that you can actually view additions or entity 
changes.

Change the display of viewports by choosing from the
following options:

ADD      - to add a new viewport up to the maximum number
           specified in CONFIG.

REMOVE   - to remove an existing viewport.

MOVE     - to move an existing viewport.

RESIZE   - to alter the size of an existing viewport.

AUTO SET - to display one of the eight predefined viewport
           configurations. This allows you to set up 
           several viewports with the same standard view 
           or views and display modes.
