In the topic in the Hacker's .CHM file titled "Set TextMerge, Set("TextMerge"), \, \\, _PreText, _Text, Set TextMerge Delimiters, " the 'Text' link in the 'See Also' section at the bottom of the topic, should be linked to the 'TEXT ... ENDTEXT' topic, rather than the TEXT topic.
Where's the CD?
Late in the production process, we discovered that the extra text added for the 6.0 version of the book made it a real challenge to produce. We chose not to skimp on the production of the book, and instead, made all of the source code, as well as the HTML Help version of the book, available online, at http://www.hentzenwerke.com. Please check there to download the code. Make sure you have the book available, as you need to prove you have purchased the book in order to access the source code and HTML Help version.
What is the purpose of the book?
The Hacker's Guide to Visual FoxPro 6.0, casually referred to as HackFox6, is the single greatest reference book ever written for FoxPro. Bar none. Ever. We're proud of the work we have done, and the help we have received from throughout the FoxPro community, in making this book the best.
When I try to order the book, my favorite (online) bookstore says the book is not available or that it may take weeks to get it. How can I order your book?
The world of merchandising books is far stranger than we would have ever anticipated. While many bookstores seem to be really challenged in ordering the book, it is available. For the fastest delivery, try http://www.hentzenwerke.com. The other online booksellers (we don't have to supply their links here, do we?) are among our biggest customers, and they, too, can deliver the book pretty quickly. Any bookstore can order the book directly from Hentzenwerke Publishing, or you can order it yourself.
