| − | If you want a complete listing of all parameter values and the pages that are using them you can build a '''permuted index'''. (Note: The category system of MediaWiki is also a permuted index). If a page uses more than one value it will appear in the result more than once. If several pages use the same value they will be listed below that value.

| − | In our example the template ''Index'' does nothing; it could, however, tell the reader, that this page belongs to a certain index group - just like mediawiki lists the categories of a page at the bottom of your wiki browser. The surrogate template we use in the DPL query constructs an [http://mediawiki.org/Extension:Array array] which is sorted and printed afterwards.

| − | The result looks like this:

| − | {{#arraydefine:inx|

| − | {{#replace:

Tree of relations, templates and categories for a given page
We show references to other pages and the use of templates.
{{#tree:root=[[DPL Example 010 page 1]] ..|
{{DPL Example 010 sub|DPL Example 010 page 1|*}}
}}
The above DPL command produces the following output:
{{#tree:root=DPL Example 010 page 1 ..|
{{#replace:* DPL Example 010 cat
}}
