How can you beat Hyperlinks, Copy / Paste of code (you can't even do that from help in IDE) and fast Searches not to mention 0 Money Units?
The way it is done in many cases: The book and a CD / DVD with the Wiki at the time of going to press. The book would be then a standard work for programming with QB64.
If there are major additions over time and the book sells well, a new edition can be made.
Free is nice, but not crucial for me personally. I prefer to have a book in front of me, and a price of around 25 to 30 dollars / euro would be acceptable for me.
