Description Mike Kaganski 2022-08-15 12:48:43 UTC 
Consider the code:

Sub TestCallingVariable
  Dim Month
  MsgBox Month(Now)
End Sub

Running this gives an empty message box.

This is a simplified user error case, where the built-in Month [1] was redefined locally as a variable. The problem here is that there is no error suggesting that Month(Now) makes no sense: Month local variable is neither a function, nor an array.

Hello Mike! It seems to me that this is part of the overall picture: Basic ignores "extra parameters".

Option Explicit
Sub Test1
  Dim a
  Msgbox a(1)              ' Empty string
  Msgbox abs(1, 2, 3, 4)   ' 1
End Sub
