If the UNCALCED record is present in the Book stream, it indicates that the Calculate message was in the status bar when Microsoft Excel saved the file. This occurs if the sheet changed, the Manual calculation option was on, and the Recalculate Before Save option was off (Options dialog box, Calculation tab).
