If you change your regional settings to use the semicolon as your list
separator, you can save as .csv and it should work. But this may affect other
programs, too--since it's a windows setting.

near the bottom.
On the other hand, if you don't want to fiddle with that setting, you could use
a macro to write your file.
Here are three sites that you could steal some code from:
Earl Kiosterud's Text Write program:
www.smokeylake.com/excel
(or directly:
http://www.smokeylake.com/excel/text_write_program.htm)
Chip Pearson's:
http://www.cpearson.com/excel/imptext.htm
J.E. McGimpsey's:
http://www.mcgimpsey.com/excel/textfiles.html
If you don't want to write your own, try Earl's program first. He has lots of
options in that program.
If you're new to macros, you may want to read David McRitchie's intro at:
