    Excel 2007
    How BF works under Excel 2007, Excel 2010 and later
    Business Functions works fine under Excel 2007 as well as previous versions as far back as Excel 97. Models developed under Excel 2003 or earlier will work fine with Business Functions.

    Currently (as at version 1.42) the only difference is the menu system, which under Excel 2007 is, of course, the new ribbon. The underlying VBA and C++ code is exactly the same. This is why, in the Business Functions directory, you will see busfun.xla, being the interface for Excel 97-2003, and busfun.xlam, the interface for Excel 2007, but only one library file, busfunlb.xll, for both versions. The installer will install the correct one for each version of Excel you have installed.

    Some time we will develop a specific Excel 2007+ version of the library. This will use exactly the same code for the functions themselves, but will be able to take advantage of Excels new larger ranges amd longer strings. This evolution will probably be invisible to you, the user. The old Excel 2003 and earlier library will always use the same codebase and will be developed concurrently.

    Essentially, the current BF for 2007 is an interfaced-tweaked version of the existing library.

    Just to repeat, there are no compatibility issues with BF with the arrival of Excel 2007.

    A couple of tips under Excel 2007
    • Press and hold the Alt key to see the keyboard shortcuts. As well as the Excel ones, BF is thoroughly keyboard shortcutted. For example, Alt-B brings up the BF Library ribbon, Alt-BH brings up BF Help (and its still context-sensitive).
    • Double clicking on the ribbon causes it to minimise, and give you more room to see your spreadsheet. You can get the ribbon back by either double clicking again, or waking it up by using a keyboard shortcut.
    • As you hover over a menu item or button (BF or Excel), a detailed tip will appear. It is actually two tips, a brief screentip and a more detailed so-called supertip.

    Large Range Limitations
    • You can refer to cells or ranges anywhere on the worksheet, up to column 16,384 (column XFD) and row 1048576.
    • You cannot have a range whose column extent is greater than 256 columns. That is because it has not yet been possible to build an optimised Excel 2007 version.
    • You cannot, in any event, have a range size greater than 10,000 cells. That is a longstanding BF limitation. We may increase this in future versions, but we are not convinced of the need and are a bit concerned about the potential performance hit.
    Our advice is not to get too carried away with the new found freedoms. The 256 column limit was a legitimate bugbear, and now its gone it is reasonable to build spreadsheets with several hundred columns, but not into the thousands. We do not think the row limit was ever a problem.
