Multiple Conditions on DO WHILE?

Reading through file names in a directory and want to exit the loop after processing the first file (for test purposes)

Did not work.

Do While FileName <> "" Or RecordCount = 1

I had to change the code to:

Do While FileName <> ""
      If RecordCount = 1 Then
         Exit Do
      End If

Did I write it wrong the first way or are multiple conditions now allowed? I didn't get a compile error.
