You are right. I just did not know how to get the var defined.
so  now I got this code for a {$$PageListCount} templ. var:

  ##  get the list of pages
 $matches = array_values(MakePageList($pagename, $opt, 0));
 $pagelistcount = count($matches);
 if (@$opt['start']) {
   if ($opt['start'] >= 0)
     $matches = array_slice($matches, $opt['start']-1);
   else 
     $matches = array_slice($matches, $pagelistcount+$opt['start']);
 }
 ##  extract page subset according to 'count=' parameter
 if (@$opt['count']) {
   list($r0, $r1) = CalcRange($opt['count'], $pagelistcount);
   if ($r1 < $r0) 
     $matches = array_reverse(array_slice($matches, $r1-1, $r0-$r1+1));
   else 
     $matches = array_slice($matches, $r0-1, $r1-$r0+1);
 }
 $savecursor = $Cursor;
 $pagecount = 0; $groupcount = 0; $grouppagecount = 0;
 $pseudovars = array('{$$PageListCount}' => &$pagelistcount,
                     '{$$PageCount}' => &$pagecount, 
                     '{$$GroupCount}' => &$groupcount, 
                     '{$$GroupPageCount}' => &$grouppagecount);

works fine.
