I am reading a programming book that was written by an author that is not around anymore and published by a company that also does not exist anymore.
This is the book.
When I load in the CD-ROM, I notice the README file. This is it:

Does this mean I can use the code for my own personal gain, or can I just toss this book and the source code that I have been modifying for a while away?
If I rearrange the code, would it help my case in making the copyright null? This means just swapping where functions are declared and/or renaming them.
Also, I do own this book and the CD.
