3. Introduction VBScript is a scripting language. A scripting language is a lightweight programming language. VBScript is a light version of Microsofts programming language Visual Basic VB Script Variables A variable is a convenient placeholder that refers to a computer memory location where we can store program information that may change during the time our script is running. Declaring Variables We declare variables explicitly in our script using the Dim statement, the Public statement, and the Private statement. For example: Dim Country Job Oriented QTP/UFT Training

4. We declare multiple variables by separating each variable name with a comma. For Example: Dim x, Top, Bottom, Left, Right Naming Restrictions for Variables Variable names follow the standard rules for naming anything in VBScript. A variable name: Must begin with an alphabetic character. Cannot contain an embedded period. Must not exceed 255 characters. Must be unique in the scope in which it is declared. Scope of Variables A variables scope is determined by where we declare it. When we declare a variable within a procedure, only code within that procedure can access or change the value of that variable. Job Oriented QTP/UFT Training

5. If we declare a variable outside a procedure, we make it recognizable to all the procedures in our script. This is a script- level variable, and it has script-level scope. Life Time of Variables The lifetime of a variable depends on how long it exists. The lifetime of a script-level variable extends from the time it is declared until the time the script is finished running. At procedure level, a variable exists only as long as you are in the procedure. Assigning Values to Variables Values are assigned to variables creating an expression as follows: The variable is on the left side of the expression and the value you want to assign to the variable is on the right. For example: Country = India Job Oriented QTP/UFT Training
