          Application No. 08/098,501                                                  


          Balzer, ¨EXDAMS - EXtendable Debugging and Monitoring System,¨ Spring       
          Joint Computer Conference, vol. 33, pp. 567-580 (1969)                      

                    Claims 1 through 22 stand rejected under 35 U.S.C. § 103 as       
          unpatentable over Padawer in view of Balzer.                                
                    Reference is made to the brief and answer for the                 
          respective positions of appellants and the examiner.                        
                                         OPINION                                      
                    We have carefully considered the evidence before us               
          including, inter alia, the arguments presented by both appellants and       
          the examiner and, based upon that evidence, we will not sustain the         
          rejection of claims 1 through 22 under 35 U.S.C. § 103.                     
                    Pointing to various portions of Padawer at pages 4-6 of the       
          answer, the examiner contends, at least with regard to the                  
          independent claims, that Padawer discloses everything but the               
          recording of the register and memory location values that are changed       
          by instructions, as claimed.  The examiner relies on Balzer for the         
          teaching of this aspect of the claimed invention, particularly              
          pointing to page 570 of Balzer and contending that Balzer teaches a         
          history tape for storing necessary information, including variable          
          values, about program actions.  The examiner then concludes that the        
          storage of register and memory location values, as recited in               
          independent claim 1 is taught and that it would have been obvious to        

                                            3
