Static V's Public declares

[Wokawidget]

What is the difference, if any, between:

Public Static Function Woof()
Dim lngID           As Long
Dim strUsername     As String
    'Code here
End Function

and

Public Function Woof()
Static lngID        As Long
Static strUsername  As String
    'Code here
End Function

Is there a difference is memory used for storing data, is one more economical than the other, or are they absolutely identical?
They both have EXACTALLY the same end result...
