    Use the OPTIONAL keyword in the argument list, for example....

    Code:
    Private Sub SomeSubRoutine(ByVal Par1 As String, Optional Par2 As Long = 0, Optional ByVal Par3 As Boolean = False)
    As with VB6, that if you make 1 argument optional, then all arguments that follow must also be optional.

    And one change from VB6, is that you must always specify the default value for the optional argument.
