Thanks.

Great site, by the way!

Yes, that's it. One of our stores sent us a spreadsheet (they could have saved it as Excel - StarOffice does have this capability).

StarOffice runs on Windows and Lunix (among others, I believe), and can be obtained for free (www.sun.com).

My preliminary tests revealed it has most of the capabilities of MS-Office, with one notable exception: Outline mode in the word processor (I use this one for a "hierarchical to-do list", one I can expand and collapse!).

I, of course, had forgotten the extensions for this office suite.

Hilmar.
