Files with the extension 
                     				.prc or 
                     				.ws are now recognized as copybooks for all projects in Visual Studio. 
                     			 
                  
 
                  			 
                  Note: If the COPY statements in your source code reference any of these files without specifying the extension, you should also
                     set the 
                     				COPYEXT"prc,ws" Compiler directive in your project.
