Is it possible to call a VB function without the parenthesis?

Question

I am looking at VB6 code and I see a statement as follows -

       Public Sub CheckXYZ(abc As Integer)

       If abc <> pqr Then SetVars abc
<         


        

Answer 1

Sub calls with parameters do not require the parenthesis. Paranthesis are only required for a function returning a result.

Private Sub Testy1()
    Function1 "Testy2" ' does not require parenthesis
    Debug.Print Function1("Testy3") ' does require parenthesis
End Sub

Private Function Function1(str as String) as Boolean
    Function1 = True
End Function
