[support] Using Drupal Pager in D5 Module

I have a custom SQL search and I use pager_query which works nicely. But how do I get the paging links to come up? I tried this:

$form['pager'] = array( '#value' => theme('pager', NULL, 10, 0) );

which I see in other modules, but nothing happens. To clarify, this code:

$form[] = array( '#value' => theme('table', array('Name'), my_module_run_search()) );

generates the search results, and in my_module_run_search() I call pager_query.

I am also wondering how the page=1 from the URL gets transferred into pager_query, because if I manually add it to the URL, I still get the first page.

Thanks for any pointers!
