rreeaaddoonnllyy builtins. Each attribute applies to all members of an array.
Arrays are assigned to using compound assignments of the form
_n_a_m_e=((value_1 ... value_n)), where each _v_a_l_u_e may be of the form [_s_u_b_-
_n_a_m_e=((value_1 ... value_n)), where each _v_a_l_u_e is of the form [_s_u_b_-
_s_c_r_i_p_t]=_s_t_r_i_n_g. Indexed array assignments do not require anything but
_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.
When assigning to an associative array, the words in a compound assign-
ment may be either assignment statements, for which the subscript is
required, or a list of words that is interpreted as a sequence of al-
ternating keys and values: _n_a_m_e=(( _k_e_y_1 _v_a_l_u_e_1 _k_e_y_2 _v_a_l_u_e_2 ...)). These
are treated identically to _n_a_m_e=(( [_k_e_y_1]=_v_a_l_u_e_1 [_k_e_y_2]=_v_a_l_u_e_2 ...)).
The first word in the list determines how the remaining words are in-
terpreted; all assignments in a list must be of the same type. When
using key/value pairs, the keys may not be missing or empty; a final
missing value is treated like the empty string.
When assigning to an associative array, the subscript is required.
This syntax is also accepted by the ddeeccllaarree builtin. Individual array
elements may be assigned to using the _n_a_m_e[_s_u_b_s_c_r_i_p_t]=_v_a_l_u_e syntax in-
