VBScript is a scripting language that can be used for both client-side and server-side programming. The document discusses VBScript variables like local and global variables, arrays, procedures, functions, conditional statements like If/Else and Select Case, and loops like For/Next loops and Do/While loops. It also covers built-in functions provided in VBScript.

- 3. VBScript Variables Avariable is a "container" for information you want to store. Naming Rules : Must begin with an alphabetic character Cannot contain a period Cannot exceed 255 characters Must be unique within its scope 12/29/10 For more QTP Scripts, www.ramupalanki.com
- 4. Lifetime OF VariablesLocal Variables: When you declare a variable within a procedure, the variable can only be accessed within that procedure. When the procedure exits, the variable is destroyed. You can have local variables with the same name in different procedures, because each is recognized only by the procedure in which it is declared. Global Variables: If you declare a variable outside a procedure, all the procedures on your page can access it. The lifetime of these variables starts when they are declared, and ends when the script is closed. 12/29/10 For more QTP Scripts, www.ramupalanki.com
- 5. Variable (Cont) Declaration:Dim Keyword is used to Declare a variable You can Assign a Value to variable directly (without declaring a variable). But not a good practice. Option Explicit Keyword is used to restrict variables to be declared before their usage. Example: Option explicit Dim var_ x var_x=1 12/29/10 For more QTP Scripts, www.ramupalanki.com
- 6. Constants Const keyword is used to declare constants. It is necessary to initialize the Constant during its declaration. You cannot change the value of constants in later script. Syntax: const x=1 12/29/10 For more QTP Scripts, www.ramupalanki.com

- 8. Arrays An arrayis a set of variables conveniently packages for easy handling Sometimes you want to assign more than one value to a single variable. Then you can create a variable that can contain a series of values. This is called an array variable 12/29/10 For more QTP Scripts, www.ramupalanki.com
- 9. Arrays (cont.) Thedeclaration of an array variable uses parentheses ( ) following the variable name. Example: dim names(2) names(0)=“Ali“ names(1)=“Imran“ names(2)=“Khan" 12/29/10 For more QTP Scripts, www.ramupalanki.com
- 10. Arrays (cont.) Anarray can be multi dimensional. There can be 60 (maximum) dimensions in an array. Multiple dimensions are declared by separating the numbers in the parentheses with commas. 12/29/10 For more QTP Scripts, www.ramupalanki.com

Editor's Notes
- #4 A variable is a &quot;container&quot; for information you want to store. A variable's value can change during the script. You can refer to a variable by name to see its value or to change its value. In VBScript, all variables are of type variant , that can store different types of data.
