How can I make old macros work with excel 2013?

Hi all,

I would like to use some old macros (Microsoft Excel 5) but can make it work with Microsoft Excel 2013. I think it is no longer compatible. Is there a way to make this old macro work with Microsoft Excel 2013? I really wanted to use the file. I have attached the file and here is the link where it came from (http://ipm.ucanr.edu/DISEASE/DATABASE/TomatoPMdoc.html)
