          Application No. 09/210,104                                 Page 2           


                                     BACKGROUND                                       
               Appellants' invention relates to a method and apparatus for            
          monitoring the execution of a program.  An understanding of the             
          invention can be derived from a reading of exemplary claim 1,               
          which is reproduced as follows:                                             
               1. An Execution Trace Facility computer system, which                  
          provides all available pertinent data required to trace a program           
          flow for malfunctions, comprising:                                          
               means for inserting said Execution Trace Facility into the             
          code of the program in a disabled mode, at various strategic                
          locations;                                                                  
               means for recompiling said program after said Execution                
          Trace Facility is inserted into said code of the said program;              
               means for using said program in a normal operating                     
          environment and for determining if a malfunction of said program            
          occurs; and                                                                 
               means for enabling said Execution Trace Facility to restart            
          said program and detect and correct said malfunction only in                
          response to a detection that a malfunction of said program has              
          occurred.                                                                   
               The prior art references of record relied upon by the                  
          examiner in rejecting the appealed claims are:
