In the Voyage Trading Plan, YARRG indicates after the commodity name
where in the YPP commodity UI each commodity can be found. First
comes the initial letter of the category:
-% my $dbh= dbw_connect('Midnight');
+% my $dbh= dbw_connect('Cerulean');
% my $getclasses= $dbh->prepare(
% "SELECT commodclass FROM commodclasses ORDER BY commodclass");
% $getclasses->execute();
