          Application No. 08/461,943                                                  


               18. A digital computer implemented method for                          
               converting a source program to an object code                          
               comprising the steps of:                                               
                    receiving the source program;                                     
                    generating a first intermediate representation                    
               of the source program;                                                 
                    identifying from either compiler directive or                     
               syntax at a selected point in said first                               
               intermediate representation of the  source program a                   
               possible asynchronous activity;                                        
                    inserting a pseudo operation responsive to                        
               identifying said possible asynchronous activity for                    
               a selected variable at said selected point in said                     
               first intermediate representation of the source                        
               program;                                                               
                    processing sequential operations of said first                    
               intermediate representation including said pseudo                      
               operation and defining an internal data structure of                   
               the source program;                                                    
                    processing said defined internal data structure                   
               and generating an optimizer data structure.
