- In your PL/I program, code a call to the built-in PLITEST subroutine, and provide the name of the attachment as a parameter
                  for the PLITEST subroutine. For example, the following PLITEST routine calls Program1, and specifies MYATTACH as the name
                  of the debuggable attachment: 
                  		  call plitest('env Program1;br 4;br 5;c',"MYATTACH", 3);
- From the 
                  		  Solution Explorer, double-click the 
                  		  Properties entry in the PL/I project, and select the 
                  		  Debug tab. 
                  		
               
- Set 
                  		  Launch to 
                  		  Wait for debuggable attachment. 
                  		
               
- Set the 
                  		  Wait for debuggable attachment field to 
                  		  Wait for ID. 
                  		
               
- In the 
                  		  ID field, type the name of the attachment identified in your program's PLITEST call. 
                  		
               
- Save your changes. 
                  		
               
- Click 
                  		  Debug > Start Debugging. 
                  		  
                  The debugger now waits for and then attaches to the next program identified by 
                     			 ID you provided. 
                     		  
                   
- Launch your program. 
                  		  
                  The debugger begins debugging at the specified point.
