+<h3><a name="posinclass">Locating commodities in the YPP client UI</a></h3>
+
+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 $getclasses= $dbh->prepare(
+%        "SELECT commodclass FROM commodclasses ORDER BY commodclass");
+%     $getclasses->execute();
+<%
+    join '; ', map { $_->[0] =~ m/^./ or die; "<strong>$&</strong>$'" }
+        @{ $getclasses->fetchall_arrayref() }
+%>.
+<p>
+
+Then, if applicable, follows a number from <strong>0</strong> to
+<strong>9</strong> indicating roughly where the commodity is in the
+list of commodities of the same class.  The number indicates which
+tenth of the list is: <strong>0</strong> for the first (top) tenth,
+<strong>1</strong> for the 2nd, and so on, up to <strong>9</strong>
+for the final tenth.
+
+<p>
+For example,
+<blockquote>
+<table><tr>
+<td>Fine pink cloth&nbsp;&nbsp;
+<td><div class=mouseover
+ title="Fine pink cloth is under Cloth, commodity 14 of 55">C 2</div>
+</table>
+</blockquote>
+indicates that Fine pink cloth can be found under Cloth,
+between 20% and 30% of the way down through the types of Cloth.
+If you mouseover that in a suitably equipped browser you should see the
+text:
+<blockquote>
+Fine pink cloth is under Cloth, commodity 14 of 55
+</blockquote>
+<p>
+
+The position indicator digit isn't shown for very small
+categories.
+
+The exact location of the commodity in the actual game
+client may vary because YARRG only considers the list of all possible
+commodities, not the list of actual offers at the island in question.
+
+Also, not all commodities are always completely categorised or
+ordered; we are working to add the additional data
