 *      _lerror - library run-time error processor.  This routine
 *                acts upon an error status as requested in the 'hndlcode'
 *                argument.  The actions are as follows:
 *
 *                MODE          ACTION
 *
 *                _LELVL_ABORT  Print the error message and then abort with
 *                              traceback.  On the YMP, a traceback will be
 *                              suppressed if _repriev is not loaded.
 *                _LELVL_EXIT   Print the error message and then call exit with
 *                              a nonzero status. This mode is used by commands.
 *                _LELVL_MSG    Print the error message and then return.
 *                _LELVL_RETURN Return without printing anything.
