Better than trace or alert, I suggest anyone Arthropod for tracing out debugging information.

It consist in one class to include in your project, and a small AIR app wich contains the console and some easy configuration.

import com.carlcalderon.arthropod.Debug;
Debug.log("My log message");

Supports logging of a lot of types of data: text messages, objects, bitmaps.
