Well... the easiest thing is to design so that you don't need to do
anything.  For example, let's say you have the directory structure:

-----
app_dir/
    list_contents
    documents/
    pictures/
    movies/
-----

Where list_contents is a DTML Method like:

-----
<dtml-in "objectIds(object_type)" prefix=obj>
    <dtml-var obj_item>
</dtml-in>
-----

Now, if you want list_contents to apply to a specific directory, you
need only cause the client to request a URL like:

app_dir/documents/list_contents
app_dir/pictures/list_contents
app_dir/movies/list_contents

It is not usually necessary to *set* the current directory if you let
Acquisition respond in the context of the client request.

If you need to use an object that regular Acquisition isn't going to
find correctly, you can use restrictedTraverse() or dtml-with.

HTH,
