Reading and/or writing a text file in javascript not working

Dear Sir,
Why this code can't be ran in my Internet Explorer?
Am I doing wrong in using ActiveXObjectScripting.FileSystemObject")?

Heya, Fuji. Welcome to TSDN!

Try OpenTextFile().

Dear Sir,
This code is executable but has wrong array's value.
Can anyone put array's value in the right place?
for example:
list[0,0] = Item001 list[0,0] = A001
list[1,0] = Item002 list[0,1] = B001
list[2,0] = Item003 list[0,2] = C001
list[3,0] = Item004 list[0,3] = D001
list[4,0] = Item005 list[0,4] = E001
stocklist.txt:
Item001|A001|99|A002|98
Item002|B001|97|B002|96
Item003|C001|95|C002|94
Item004|D001|93|D001|92
Item005|E001|91|E002|90

Heya, Fuji.

What do you want your code to do? Give an example.
What is your code doing that you don't want it to do? Give an example.
What is your code *not* doing that it is supposed to? Give an example.

Dear Sir,

What do you want your code to do? Give an example.
In this example, I want this code to do that is just like this.
data2[0,0] = array00
data2[0,1] = array01
data2[0,2] = array02
data2[0,3] = array03

What is your code doing that you don't want it to do? Give an example.
data2[0,0] = array10
data2[0,1] = array11
data2[0,2] = array12
data2[0,3] = array13

What is your code *not* doing that it is supposed to? Give an example.
After runnung this code in IE, "document.write(data2[0,0] + data2[0,1] + data2[0,2] + data2[0,3] + data2[0,4]);" prints out the result is not supposed to have.
What I want is
data2[0,0] = array00
data2[0,1] = array01
data2[0,2] = array02
data2[0,3] = array03
What do not I want is
data2[0,0] = array10
data2[0,1] = array11
data2[0,2] = array12
data2[0,3] = array13

<html>
<head><title>JavaScript Example</title>
</HEAD>
<script language=javascript>
data1 = new Array();
data2 = new Array();
function javascriptarray(){
data1[0] = "array:"+0+0;
data1[1] = "array:"+0+1;
data1[2] = "array:"+0+2;
data1[3] = "array:"+0+3;
data2[0,0] = data1[0];
data2[0,1] = data1[1];
data2[0,2] = data1[2];
data2[0,3] = data1[3];

data1[0] = "array:"+1+0;
data1[1] = "array:"+1+1;
data1[2] = "array:"+1+2;
data1[3] = "array:"+1+3;
data2[1,0] = data1[0];
data2[1,1] = data1[1];
data2[1,2] = data1[2];
data2[1,3] = data1[3];

document.write(data2[0,0] + data2[0,1] + data2[0,2] + data2[0,3] + data2[0,4]);
}
