To debug the test case, you must use the Debug option within the 
               		Micro Focus Unit Testing window. 
               	 
            
 
            	 
            
               -  
                  		  Just as you would when debugging any other program, you need to set a breakpoint beforehand; if 
                  			 TestAIRCODE.cbl is not already displayed in the editor, open it from Solution Explorer. 
                  		   
                  		    
                  			 
                  The test program is displayed in the editor. 
                     			 
                   
-  
                  		  Set a breakpoint on the line that starts: 
                  		   
                  		    
                  			 string "Incorrect distance in kilometers returned... 
-  
                  		  In the 
                  			 Micro Focus Unit Testing window, right-click 
                  			 TESTAIRCODE, then select 
                  			 Debug Test. 
                  		   
                  		    
                  			 
                  The debug engine starts, and test execution stops at the breakpoint.

                  		  Hover over the 
                  			 distance-km variable to see the distance between the two airports (Heathrow and Seattle). 
                  		   
                  		   The distance has been calculated as 7,703 (which happens to be the correct distance), and so the code is executing as it should.
                  It is also asserting a failure correctly, but that is because the wrong value was being tested for (it's testing for the distance
                  in miles - 4,787), as you can see from the following line: 
                  			 if function numval(distance-km) not equal 4787...

                  			 F5 to execute the rest of the test case.
