A variable of type HANDLE that represents the handle of the dynamic data-source object.
An expression of type CHARACTER that evaluates, at run time, to the name of the widget pool in which the dynamic data-source object is created.
If you do not specify a widget pool name, the dynamic data-source object is created in the closest unnamed widget-pool, by default. The object goes away when its widget pool goes away or when you delete it using the
DELETE OBJECT statement.
