Object on Screen 1 was initially created with a device object
(defining object properties) and a screen object (defining screen
location and input type).
Object on Screen 1 was defined as a global object by clicking the
Mark for Global Selection in the object’s Options dialog.
Global object is reused on Screen 2. Global objects are accessed
from Global Objects dialog. A screen device was created linking
the global object to the new screen.
Global object is reused again on Screen 3. Another screen device
was created linking the global object to the new screen.
If the properties of a global object are changed, all other links to that
object are also updated.
