VBScript Programs

Example

Subroutine
This subroutine does not return a value.
Function Program
If you want to return a value, you can use a function program.

VBScript Programs

We can use two types of programs: subroutine and function program.

Subroutine:

  • It is a series of statements enclosed within the Sub and End Sub statements.
  • It can perform certain operations but will not return a value.
  • It can have parameters passed to the subroutine through program calls.
  • If not, it must have empty parentheses
Sub mysub()
 some statements
End Sub

Sub mysub(argument1, argument2)
 some statements
End Sub

Function Program:

  • It is a series of statements encapsulated within the Function and End Function statements.
  • It can perform certain operations and return a value.
  • It can have parameters passed to it through program calls.
  • If not, it must have empty parentheses
  • By assigning a value to the function program name, it can return a value.
Function myfunction()
 some statements
 myfunction=some value
End Function

Function myfunction(argument1,argument2)
 some statements
 myfunction=some value
End Function

Calling Subroutines or Function Procedures

You can call a function in this way:

name = findname()

This function is named "findname", the function will return a value, which will be stored in the variable "name".

Or you can do it this way:

msgbox "Your name is " & findname()

We called a function named "findname", the value returned by this function will be displayed in the message box.

You can call the subroutine in this way:

Call MyProc(argument)

Or, you can also omit the Call statement:

MyProc argument
