Coding Question

[Evan]

This is a example I was just given.
Ive seen people do this twice now.

Private Function FileExists(FullFileName As String) As Boolean 
On Error GoTo MakeF 
'If file does Not exist, there will be an Error 
Open FullFileName For Input As #1 
Close #1 
'no error, file exists 
DoExists = True 
Exit Function 
MakeF: 
'error, file does Not exist 
DoExists = False 
Exit Function 
End Function

The last 2 lines dont make sense to me...

Exit function
End Function

Why exit the function when its ending anyway???
