>&#13;     Syntax "index =&#62; values", separated by commas, define index
     and values. index may be of type string or numeric. When index is
     omitted, a integer index is automatically generated, starting
     at 0. If index is an integer, next generated index will
     be the biggest integer index + 1. Note that when two identical
     index are defined, the last overwrite the first.

>&#13;     The following example demonstrates how to create a
     two-dimensional array, how to specify keys for associative
     arrays, and how to skip-and-continue numeric indices in normal
     arrays.

     Note that index '3' is defined twice, and keep its final value of 13.
     Index 4 is defined after index 8, and next generated index (value 19)
     is 9, since biggest index was 8.
