               Application No. 08/370,963                                                                                            


                       The appellants' invention relates to a profile based optimization of shared libraries.                        
               An understanding of the invention can be derived from a reading of exemplary claim 1,                                 
               which is reproduced below.                                                                                            
                       1.      A method of operating a digital computer to provide instrumentation                                   
                       data for a shared library running in an environment in which programs are                                     
                       loaded and unloaded by a loader, said environment supporting the operation                                    
                       of at least one program in addition to said shared library, said program                                      
                       utilizing at least one function provided by said shared library, said                                         
                       environment including means for storing a predetermined environment                                           
                       variable that may be read by any program running in said environment, said                                    
                       method comprising the steps of:                                                                               
                               causing said loader to examine said environment to determine if said                                  
                       predetermined environment variable has been set; and                                                          
                               storing profile based optimization data stored in said shared library                                 
                       code in a location specified by said predetermined environmental variable if                                  
                       said predetermined environmental variable was present in response to a                                        
                       command being sent to said loader.                                                                            

                       The prior art references of record relied upon by the examiner in rejecting the                               
               appealed claims are:
