This is a fantastic book for people that want to learn Director from scratch. It assumes you know nothing of the program to begin with, and it guides you to mastery, one step at a time.
I would heartily recommend this book to programmers that have never worked with Lingo before, but look for a book that covers more or less everything. The book presents numerous examples of applications, that will little more effort can look very professional. Six chapters offer complete applications (games, educational apps, business, grafx and sound apps) that can really help you start rapidly. Excellent appendices complete this already full book.
Of all the programming books I have bought, this one has won its place just by the monitor - a rare honour. Whenever I am programming Director, this is a reference I must have handy.
I have recommended this book to all my students, as I recommend it to you! Congratulations Mr. Rosenberg!
