Chapter 5. Using Functions
When programming, you may find yourself using the same chunks of code repeatedly—either by copying and pasting them or by rewriting the same lines of ActionScript. There is a way to write ActionScript just once and reuse it anytime with a single action. You do this with functions and the action by which you execute a function is a call or a function call. Functions are real time-savers—during both development and code maintenance—because they reduce the amount of code you need to write or modify.
