 *                       for their parameters - 1 or higher (for arrays)      *
 *      num       - [IN] parameter number; for item keys and OIDs the level   *
 *                       will be 0; for their parameters - 1 or higher        *
 *      quoted    - [IN] 1 if parameter is quoted; 0 - otherwise              *
