Anyone happen to have the code from this book, bought an old copy online but all the code links I can find are broken or don't exist anymore. Thx!

Google is an excellent tool. http://download.e-bookshelf.de/download/0000/5685/80/L-G-0000568580-0002381845.pdf

I eventually found the old Wiley link: https://onlinelibrary.wiley.com/doi/pdf/10.1002/9781119196594.app1
