After verifying a project, you can ensure a closed system by including referenced or referencing objects in the project. The
               objects to be included must also have been verified, so it's best to verify every project in the workspace before including
               objects. 
               	 
            
 
            	 
            You can include all referencing objects or only “directly referencing” objects: if program A calls program B, and program
               B calls program C, A is said to directly reference B and indirectly reference C. 
               	 
            
 
            	 
            To include in a project: 
               	 
            
 
            	 
             
               		
               - Every object referenced by the objects in the project (including indirectly referenced objects), select the project in the
                  Repository Browser and choose 
                  		  Project > Include All Referenced Objects. 
                  		
               
- Every object that references the objects in the project (including indirectly referencing objects), select the project in
                  the Repository Browser and choose 
                  		  Project > Include All Referencing Objects. 
                  		
               
- Every object that directly references the objects in the project, select the project in the Repository Browser and choose
                  
                  		  Project > Include Directly Referencing Objects.
