<p>
<h5>
Description:
</h5>
Returns the element at position index in the array passed. Arrays are treated
as base-one, so <b><tt>index</tt></b> set to 1 would return the first element.
<p>
Arrays can also be accessed through the <b><tt>[]</tt></b> operators. So
<b><tt>array[index]</tt></b> would return the same as <b><tt>Array'Get(array, index)</tt></b>.

<p>
<h5>
Description:
</h5>
Sets the element at position index in the array passed to the value
passed in as argument to element. Arrays are treated
as base-one, so <b><tt>index</tt></b> set to 1 would set first element.
<p>
Arrays can also be accessed through the <b><tt>[]</tt></b> operators. So
<b><tt>array[index] := element</tt></b> would do the same as <b><tt>Array'Set(array, index,element)</tt></b>.
