VBScript is a native Windows programming language which is mainly used to create web server applications. VBScript is integrated into HTML files, and it's pretty straightforward. Note that VBScript is different from Visual Basic, which is used for desktop programming.
Steps
Part 1 of 5: Setting up the Development Environment
Step 1. Get a good code editor
You can use Notepad, but a more robust editor will allow you to view the syntax of the VBScript code more easily.
Step 2. Install Internet Explorer
It is the only browser that supports VBScript, as it is a Microsoft proprietary product. You will need to install this program to see VBScript in action.
Internet Explorer is only supported by Windows, so it will be easier to follow these steps on a Windows computer
Step 3. Learn basic VBScript practices
There are many important basic concepts that will be useful to you before you throw yourself headlong into programming.
- Use '(apostrophe) to designate a comment. All lines starting with an apostrophe are comments, and are not considered part of the program. Use the comments often to help other developers - and yourself - understand what the code does.
- Use _ (underscore) to extend the term by a line. The end of a line of code is typically indicated by simply moving to the next line, but if the line becomes very long and needs to continue on the next line, write a _ at the end of the line to continue.
Part 2 of 5: Creating a Basic Page
Step 1. Create an HTML page
VBScript exists within HTML websites. In order for your code to work, you will need to create an HTML file that you can open in Internet Explorer. Open the code editor and enter the following text:

Step 2. Add VBScript tags
When you create a web page with VBScript, you need to tell the browser that you are going to insert a script. Insert the tag in your HTML source:

Step 2. Add the text you want to display
Between the brackets, enter the text you want to display on the screen. Enclose the text in question marks to indicate it as a string.

Step 3. Open the HTML file in your browser
Save the code as an. HTML file. Open the saved file using Internet Explorer. The page should show Hello World! in plain text.
Part 4 of 5: Using Variables
Step 1. Declare your variables
Variables allow you to store data that you can recall and manipulate later. You will need to declare the variables with the statement dim before you can assign values to them. You can declare multiple variables at once. Variables must start with a letter, which can be up to 255 characters long. Next, we will create the "age" variable:

Step 2. Assign values to variables
Now that you have declared the variable, you can assign it a value. Use the = symbol to do this. You can use the Write command to display the variable on the screen and verify that everything works.

Step 3. Manipulate your variables
You can use mathematical expressions to manipulate the data you have stored in your variables. These expressions work like basic algebra. You will need to declare all variables, including the response, before using them.

Step 4. Create an array
An array is essentially a table that contains more than one value. It is then considered as a single variable. Like variables, the array must first be declared. You will also need to indicate the number of values that can be stored in the array (including 0 as the first number). You can then recall the data stored in the array later.

Step 5. Create a two dimensional array
You can create an array with multiple dimensions to store more data. When you declare the array, you will need to indicate the number of rows and columns contained within.

Part 5 of 5: Using Procedures
Step 1. Learn the difference between the "sub" and "function" procedures
These two types of procedures allow the program to perform actions.
- Sub procedures can perform actions, but they cannot return a value to the program.
- Function procedures can call other procedures and return values.
Step 2. Write and call a sub procedure
You can use these procedures to create tasks that your program can call later. Use the Sub and End Sub statements to identify the sub procedure. Use the statement Call to activate the sub procedure.

Step 3. Create a Function procedure
A Function procedure allows you to execute commands and return values to the program. Function procedures are the ones that form the body of your program. Use the statements Function and End Function to identify the contents of the function.
