To create a multi-dimension array simply specify the number of columns and rows you want the array to have.

myArray(2,3) would have 2 columns and 3 rows, this would basically be like a regular array that has 3 (0-3) elements, but with 2 elements for each row.

myArray(2,3) would physically look like this:
(with the text in the cells representing the ordinal location)

0,0	1,0	2,0
0,1	1,1	2,1
0,2	1,2	2,2
0,3	1,3	2,3

And here is some ASP code that demonstrates the use of a multi-dimensional array:

Dim myArray(2,3)

'myArray(col,row)
'Array def is (dept,item,cost)
myArray(0,0) = "housewares"
myArray(1,0) = "sauce pan"
myArray(2,0) = "22.50"
myArray(0,1) = "housewares"
myArray(1,1) = "toaster"
myArray(2,1) = "12.50"
myArray(0,2) = "housewares"
myArray(1,2) = "wooden spoon"
myArray(2,2) = "4.50"
myArray(0,3) = "housewares"
myArray(1,3) = "oven cleaner"
myArray(2,3) = "2.50"

Response.Write("<table border=2>")
Response.Write("<tr><td>Row</td><td>Department</td>")
Response.Write("<td>Item Name</td><td>Cost</td></tr>")

For i = 0 to UBound(myArray, 2)
    Response.Write("<tr><td>#" & i & "</td>")
    Response.Write("<td>" & myArray(0,i) & "</td>")
    Response.Write("<td>" & myArray(1,i) & "</td>")
    Response.Write("<td>" & myArray(2,i) & "</td></tr>")
Next

Response.Write("</table>")


The above yields the following result:

Row	Department	Item Name	Cost
#0	housewares	sauce pan	22.50
#1	housewares	toaster	12.50
#2	housewares	wooden spoon	4.50
#3	housewares	oven cleaner	2.50
