          Appeal No. 97-2466                                        Page 18           
          Application No. 08/461,943                                                  


          inserting a legality assertion.  An assertion is a “Boolean                 
          statement in a program that tests a condition that should, if               
          the program is operating correctly, evaluate as true.”                      
          Microsoft Press Dictionary 28 (1994).  It is neither a store                
          instruction nor a reference instruction.  The examiner’s                    
          opinion that the variable v is a pseudo reference to z,                     
          (Examiner’s Answer at 12), in the bind statement bind var z to              
          v on page 760 of Cordy is irrelevant.  Because the bind                     
          statement is not a legality assertion, it cannot be a pseudo                
          operation of any sort including a pseudo reference                          
          instruction.                                                                


               For the foregoing reasons, the examiner failed to show                 
          that Pyster and Cordy teach or would have suggested the last                
          two steps of claim 2 and its dependent claims 4-7, the last                 
          step of claim 13 and its dependent claim 15, or the last step               
          of claim 14 and its dependent claim 16.  Accordingly, we find               
          that the examiner’s rejection of these claims does not amount               
          to a prima facie case of obviousness.  Because the examiner                 
          has not established a prima facie case, the rejection of
