These are Excel data files (.xls) that demonstrate the add-ins.
Most of them are illustrated in the Computations section of
this site. Some of the files have been compressed and stored
with the (.zip) suffix. Download by clicking on the add-in name.
The files may be expanded with the free Aladdin
Expander. Save these files to a folder to your hard disk
so you can view and change the files. The files are also included
in the jensen.lib archive.
