1.6 SAMPLE DATA SETS

A number of demonstration data sets are included with this distribution. Several of these data sets are used by the demonstration "GO" files, above. The data sets should be accessible simply by typing the Ferret command

yes? USE data_set_name
for example:

yes? USE coads_climatology
