Hi Ajimmo
You may be happy with Excel 4 and it may do all that you need. But it's
really antique and served its time well. Now let it rest and take advantage
of the inventions of the last decade. Even freeware applications perform
better than Excel 4.
Newer Windows Excel file formats are
Excel 5 + Excel 7 (aka Excel 95). Multiple worksheets in a workbook. Don't
buy those unless you're a collector like me.
and
Excel 2000 + Excel XP + Excel 2003.
The latest version is all any authorized reseller will sell you. If you go
to the secondhand market, note that XP and 2003 have "product activation" in
it, and if the software has been activated already then you may have
problems or even a worthless piece of software.
2000 was a very good year. If I had to choose a single version, and
sometimes I do; Excel 2000. It will open and work with all Excel files from
all versions, no problems. (If we leave VBA out of the discussion that is,
and we do)
If youy're using a Mac, then money is not an issue anyway. Buy Excel 2004,
it's great.
HTH. Best wishes Harald
