This may do the trick


procedure EraseAndFillWL(WLNumber, Filter)
{
  s = 0;
  Actn = 0;
  if(Actn = Status("action") == 4)
  {
    if( s = Status("stocknum") == 0 )
    {
      List = CategoryGetSymbols (categoryWatchlist, wlnumber);
      for(i = 0; (Symbol = StrExtract(List, i)) != ""; i++)
      {
        CategoryRemoveSymbol (Symbol,categoryWatchlist, wlnumber);
      }
    }
  }

  if(  LastValue (Filter)) 
  { 
     CategoryAddSymbol( "", categoryWatchlist, WLNumber); 
  } 
}


wlnumber = CategoryFind("My Watch List", categoryWatchlist );

Filter = ....

EraseAndFillWL(WLNumber, Filter);
