• Introduction
• VBScript is a scripting language.
• A scripting language is a lightweight programming language.
• VBScript is a light version of Microsoft’s 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
• 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 variable’s 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
• 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”
