Thank you very much for the message @nicholaswogan ,
true, strangely, the original link does not work any more. Fortunately, I have downloaded their whole website (the latest version) of dvode before.
Now I pushed it to a new gitlab repo, you could download it from the link below,
In the folder VODE_F90 Support Page , double click index.html,
then you should see the whole original website, and you can download all the corresponding files locally.
Hope that helps
