Looping in a script

Hi

I am trying to write a script to delete the results of a saved search but its only deleting 500 records and then fails.

Please help.

Here's the script:

"
function executeSavedSearch()
{
var results = nlapiSearchRecord('itemfulfillment', 535, null, null);
var maxrec = 300;
    var requeue = false;
    var context = nlapiGetContext();
var len = results.length;

  if(results == null )
  return true;

  // If search result length > 300 we want to requeue.
  if( results.length >= maxrec)
  requeue = true; 

  if ( len < maxrec ) maxrec = len;
  nlapiLogExecution('DEBUG', '-- Search Length= --', len);
  // Now go thru each result set of the search and process
 
for ( var i = 0; results != null && i < len; i++ )
