This is a series of VBScript statements enclosed through the Function & End Function statements. A Function procedure is same to a Sub procedure, however can also return a value. This can take arguments (variables, constants or expressions which are passed to it by a calling process). If a Function procedure has no arguments, its Function statement has to comprise an empty set of parentheses (). A Function returns a value through assigning a value to its name in one or more statements of the process. The return type of a Function is always a Variant.

The result of calculation is returned to the calling process and displayed in a message box.
Sub ConvertTemp()
temp = InputBox("Please enter the temperature in degrees F.", 1)
MsgBox "The temperature is " & Celsius(temp) & " degrees C."
End Sub
Function Celsius(fDegrees)
