Here's a key to the markup:
	[page-number]: serious technical mistake
	{page-number}: minor technical mistake
	<page-number>: important language/formatting problem
	(page-number): language change or minor formatting problem
	?page-number?: reader question or request for clarification


Confirmed errors:


(27)  Example 3-2 second line of code;
var today:Number is missing a ; at the end.


[36]  End of "Why Post-Colon Syntax?" paragraph;
In a place where Colin is talking about AS 2.0 post-colon syntax,  JavaScript 2.0 and
ECMAScript specification, it appears the icon that relates the current discussion to
AS 1.0.

Colin says: This error report is correct. There should be no note icon at all.


{237}  In figure 8.1, the parenthesized text in the bottom-right most box
should read:

(SomeConcreteType used via composition)

not:
(SomeAbstractType used via composition)


(298)  1st paragraph, second line;
"CombBox" should be "ComboBox"


{325}  2nd paragraph;
"which is much tidier and easier to understand than:
var av:Avatar = someMovieClip.attachMovie("AvatarSymbol", "avatar", 0);
av.init(100,100);"

In my opinion, it should be:

"which is much tidier and easier to understand than:
var av:Avatar = Avatar(someMovieClip.attachMovie("AvatarSymbol", "avatar", 0));
av.init(100,100)"

Because the former cause a type mismatch error.


(371)  last paragraph;
"As a matter of good form, the 'handleMessage()' method should be declared
private so that it cannot be accessed by other classes. Code external to the
Logger class should use one of the five logging methods (namely fatal(),
error(), warn(), info() or debug())."


{433, 428}  figure 19-1 and 19-2;
in the figures, the description of the arrow pointing up to the "EventListener" box
at the top right should read "extends" not "implements".
