    Notes: Read this before you run this sample.                      
           The database resides in the ets/sasmisc folder. You        
           must copy the database to a writeable folder before        
           using it. Then define your Windows system environment      
           variable, HAVER_DATA, to the path of your                
           writeable folder containing                                
           the haverw.dat and haverw.idx files (Haver database files).                                     
           To assign a fileref to the external file to be processed,  
           use the following form of the libname statement:
       
libname lib1 sasehavr "%sysget(HAVER_DATA)"
        freq=week.6 
        force=freq 
        start=20040102 
        end=20041001 
        group="F*";
