Each area instance version contains an instance of the area root class that is identified as the root object. Once an area handle has been bound to an existing area instance version, you can obtain a reference to the root object by accessing the ROOT attribute (or even using the GET_ROOT method) of the area handle. The root object can then contain and/or return object and data references (from Release 7.0) to additional objects of the area instance version.

The root object has to be defined with the SET_ROOT method of the area handle before the lock is released with the DETACH_COMMIT method of the area handle after change accesses.
