MACROMEDIA FLASH 8-LEARNING ACTIONSCRIPT 2.0 IN FLASH Manual page 170

To create a basic multidimensional array and retrieve elements from the array:
1. Create a new Flash document, and save it as multiArray1.fla.
2.
Add the following ActionScript to Frame 1 of the Timeline:
var twoDArray:Array = new Array(new Array("one","two"), new
Array("three", "four"));
trace(twoDArray);
This array,
twoDArray
arrays consisting of two elements. In this case,
two nested arrays.
3. Select Control > Test Movie to test the code. You see the following display in the
Output panel.
one,two,three,four
4. Return to the authoring tool and open the Actions panel. Comment out the
statement, as shown below:
// trace(twoDArray);
5.
Add the following ActionScript at the end of your code on Frame 1 of the Timeline:
trace(twoDArray[0][0]); // one
trace(twoDArray[1][1]); // four
To retrieve elements of a multidimensional array, you use multiple array access (
operators after the name of the top-level array. The first
level array. Subsequent array access operators refer to elements of nested arrays.
6.
Select Control > Test Movie to test the code. You see the following display in the
Output panel.

You can use nested

you how.
To create a multidimensional array using a for loop:
1.
Create a new Flash document, and save it as multiArray2.fla.
2.
Add the following ActionScript to Frame 1 of the Timeline:
var gridSize:Number = 3;
var mainArr:Array = new Array(gridSize);
var i:Number;
var j:Number;
for (i = 0; i < gridSize; i++) {
mainArr[i] = new Array(gridSize);
