       One dimensional _a_r_r_a_y contains the elements to be  sorted.
       _l_e_n  is the number of elements in the array.  _i_s_i_z_e is the
       size of an element, typically -

            4 for iinntteeggeerr and rreeaall
            8 for ddoouubbllee pprreecciissiioonn or ccoommpplleexx
            16 for ddoouubbllee ccoommpplleexx
            (length of character object) for cchhaarraacctteerr arrays

       _C_o_m_p_a_r is the name of a user supplied  integer*2  function
       that will determine the sorting order.  This function will
       be called with 2 arguments that will be elements of _a_r_r_a_y_.
       The function must return -

            negative if arg 1 is considered to precede arg 2
            zero if arg 1 is equivalent to arg 2
            positive if arg 1 is considered to follow arg 2

       On return, the elements of _a_r_r_a_y will be sorted.
