    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*";

        end=20041001
        group="F*";
