Unlike some others I found the basic listings to be very useful indeed. I did have a few problems with LDP but after more than a little debugging it works quite well. This book covered the topic better than I expected, more than enough for an interested amateur. One thing I would like, if David B.Weems is still alive... a web site where I could download the source code for both versions of LDP. C'mon Weemsy mate, you can do it...
