Existing .xls files made with earlier versions will open in compatibility

New files created in 2007 and saved in 2007 format(s) will (should) have the
extended limits.

I have 2007 on my computer and it has 65536 rows and 256 columns, just like
the 2002 version I had before. How do I get the full 2007 rows and columns?
Thank you for your time. Jim
