Your book was the first I ever bought about programming. I don't think I ever wrote a line of code from the book but it illustrated basic programming concepts that inspired me to continue development. Very impressed to read that you were only 14 when you wrote it, as I was probably only 14 when I bought it.
I had no idea the author was 14 when he wrote it. I was reading it when I was only three years younger as my first programming book. Unfortunately it wasn't exactly what I was looking for, but it definitely helped me get started in the world of programming.
