>I am pleased to announce on behalf of the authors of “Hacker’s Guide to Visual FoxPro” (Tamar Granor, Ted Roche, Della Martin, and me, with contributions from Steven Black) that the book is now open source: https://hackfox.github.io/.

Thanks for that Doug, and thanks to the other authors. I've had the book for years, and it's a great read.
Thanks for the open source version of SDT too. A valuable tool and well worth using.

Ian.
