        Arrays  are  assigned  to  using  compound  assignments  of  the   form

        _s_t_r_i_n_g.  When assigning to indexed arrays, if the optional brackets and
        subscript are supplied, that index is assigned to; otherwise the  index
        of  the element assigned is the last index assigned to by the statement
        plus one.  Indexing starts at zero.
