Typographical Conventions

In order to indicate the various syntactic components of ActionScript, this tutorial uses the following conventions:

• Constant width for code samples, clip instance names, frame labels, property names, and variable names.
• Italic for function names, method names, class names, layer names, filenames, and file suffixes such as swf.
• Constant width bold for code that you must type when following a step-by-step procedure.
• Constant width italic for code that you must replace with an appropriate value (e.g., your name here) or for variable and property names referenced in a code comment.
• Method and function names are followed by parentheses.

Pay special attention to notes set apart from the text with the following icons:
