            _D_e_s_c_r_i_p_t_i_o_n

                 'Declared' tests for the existence of a shell variable named
                 <variable_name>.   If the variable exists, 'declared' prints
                 "1"; otherwise it prints "0".

                 If <level_offset> is omitted, 'declared' examines all  lexic
                 levels  for  <variable_name>.   Otherwise,  only  the  level
                 specified (<current_level> -  <level_offset>)  is  searched.
                 (See   'arg'   for   a   more  complete  discussion  of  the
                 <level_offset> mechanism.)
