Hi All,

There is alot of documenation that accompanies MS Office as well as on MSDN
that describe the Excel/VBA object model but none of the documentation state
what versions of excel/MS Office these object model is compatible with.

Without this documentation, (and of course other than just simply testing
your code across the MS Office product line) when developing VBA application
for excel using various objects in the excel/vba object model, how do we
ensure backward compatibility so that our project/workbook will work on older
versions of excel?

Thanks
