Chapter 17
The designers of Flash included editing and debugging features to
make debugging easier. You can quickly set and remove breakpoints to
check different parts of your code to determine if it’s working correctly.
Flash uses a different debugger for ActionScript 3.0 files (FLA or AS)
than it does for ActionScript 2.0 files. The functionality is similar, but the
look and feel is different. The debugger for ActionScript 3.0 uses the
Debug workspace that displays the Debug Console, Variables, and
Output panels along with the Actions panel or Script window. The
Debug Console displays the call stack, scripts containing the functions
in the call stack, and contains buttons to step through the code. The
call stack shows the current list of nested function calls ready for exe-
cution. The Variables panel displays variables and their current values.
When a problem is encountered, Flash displays the line of code in the
Compiler Errors panel. Double-click the error to view it in the code.

When a problem is encountered, Flash displays the location and
description of the warnings and errors in the Compiler Errors panel. In
the Compiler Errors panel, you can show or hide warnings or errors
(
New!
), scroll through each one (
New!
), and display/highlight them in
the code (
New!
). You can also manage the types of compiler warning
that appear in the Compiler Errors panel by setting options in the
Publish Settings dialog box. Two options are available: Strict Mode and
Warnings Mode. Strict Mode reports warnings as errors, while
Warnings Mode reports extra warnings for discovering incompatibili-
ties when updating ActionScript 2.0 code to ActionScript 3.0.
