    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 haverd.dat and haverd.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=daily start=20041101 end=20041231;

----------------------------------------------------------------*/

libname lib1 sasehavr "%sysget(HAVER_DATA)"
        freq=daily start=20041101 end=20041231;

data hwoutd;
   set lib1.haverd;
   where date  between '01nov2004'd and '01dec2004'd;
run;

title1 'Haver Analytics Database, Frequency=daily, infile=haverd.dat';
title2 '   Define a range inside the data range for OUT= dataset';
title3 '   Using the START=20041101 END=20041231 LIBNAME options.';
title4 'Subset further: where date between 01nov2004 and 31dec2004.';
