I would like to know the hexidecimal values of some new file format constants
in Excel 2007.

- xlOpenXMLWorkbook
- xlExcel8

I would like to save a worksheet as an (old) XLS file in Excel 2007 from my
Delphi component so I need to now the hexadecimal value of xlExcel8.

I also noticed that saving a file with the xlExcel9795 constants gives an
exception. Doesn't support Excel 2007 this any more ?
