The SASEHAVR Interface Engine

You can use the SOURCE= or DROPSOURCE= option to select specific variables that belong to a certain source, similar to the way you use the KEEP= or DROP= option.

libname lib1 sasehavr "%sysget(HAVER_DATA)"
        freq=daily
        start=20041101
        end=20041223
        source="FRB";

data hwoutd;
   set lib1.haverd;
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=20041223 LIBNAME options.';
title4 '   Subset further: Using source="FRB" LIBNAME option';
proc print data=hwoutd;
run;

Output 49.9.1 shows two series that are selected by using SOURCE="FRB" in the LIBNAME statement.
