Running subsequent examples
Having developed and run the "Hello World" ActionScript 3.0 application, you should have
the basic knowledge you need to run the other code examples presented in this book.
Subsequent code examples will not be presented in a step-by-step tutorial format as this one
was. The relevant ActionScript 3.0 code in each example will be highlighted and discussed,
but instructions about running the examples in specific development environments won't be
provided. However the example files distributed with this book will include all of the files you
need to compile and run the examples easily in your chosen development environment.
