When you finish using a data object, you must terminate access to the object. When you terminate access, window services returns to the system any virtual storage it obtained for the object: storage for a temporary object or storage for a scroll area. If the object is temporary, window services deletes the object. If the object is permanent and window services dynamically allocated the data set when you requested access to the object, window services dynamically unallocates the data set. Your window is no longer mapped to the object or to a scroll area.
When you terminate access to a permanent object, window services does not update the object on DASD with changes that are in a window or the scroll area. To update the object, call CSRSAVE before terminating access to the object.
To terminate access to an object, call CSRIDAC and supply a value of END for operation_type. To identify the object, supply an object identifier for object_id. The value you supply for object_id must be the same value CSRIDAC returned when you obtained access to the object.
Upon successful completion of the call, the storage used for the window is available for other use, perhaps as a window for viewing a different part of the same object or to use as a window for viewing a different object.
