You can download the Random Numbers Race from this page.
RAND01.XLS is an Excel 5 workbook (17 Kb in a ZIP archive) I've cooked up to illustrate
some of the advantages of using arrays while manipulating Worksheets.
There is also some interesting use of the Excel Graph object.
All the "source code" is there in VBA. Enjoy. Email me if you download it
and let me know what you think about it!
