     * This program is used to list the mtpool. It can be  *
     * called in the following way :                       *
     *                                                     *
     *      <outfile>=listmtpool                           *
     *                                                     *
     * Errormessages are :                                 *
     *      *** Mtpool does not exist                      *
     *      *** Connect error = <outres>                   *
     *                                                     *
