VBScript

Introduction

• (^) Visual Basic Script (VBScript) is a subset of Microsoft Visual Basic® used in World Wide Web XHTML documents to enhance the functionality of a Web page
• (^) Microsoft’s Internet Explorer Web browser contains a VBScript scripting engine (i.e., an interpreter) that executes VBScript code

• (^) VBScript’s arithmetic operators are similar

to the JavaScript arithmetic operators.

• (^) Two major differences are
  • The division operator , ** , which returns

an integer result.

• The exponentiation operator , ^ , which

raises a value to a power.

VBScript’s comparison operators

• (^) Only the symbols for the equality operator and the inequality operator are different in JavaScript.
• (^) In VBScript, these comparison operators may also be used to compare strings.

• (^) VBScript provides 2 operators for string

concatenation

• Plus sign, +
• Ampersand ,&, formally called the

string concatenation operator.

s1 = "Pro"

s2 = “gram”

s3 = s1 & s2 or s3 = s1 + s
