This is a user-defined member associated with all objects. It is internally a reference to an Object, so you'll want to store your data to this member with sePutPointer and retrieve it with seGetPointer. It allows you to store arbitrary user data with ScriptEase objects in your application. This is commonly used when designing custom object classes specific to your application and is explored more fully in Chapter IX, Objects. All stock ScriptEase objects, described below, do not have an SE.OBJECT_DATA member, only user objects have one.
