框架在导航型课件开发中的核心作用

利用Authorware编写结构复杂的综合程序时，要做到所编写的程序结构简洁明了、易读性强、便于多人同时开发和以后的修改，离不开框架（含导航图标）的灵活使用．系统变量和系统函数是Authorware的高级应用，而框架则是编写Authorware程序的一个核心和支架，程序的各功能模块通过支架从而便于组织和控制。尤其是在课件开发中框架的作用和地位对编程是很重要的．

Framework plays the central role for the development of courseware in the tree structure

The flexible use of the framework icons （including navigation icon） is of vital importance to a clear, concise and readable programme while authorware is adopted in exploiting some integrated programmes of complexity and rich media. The system variables and system function are the core function of authorware, and the framework icon is a platform of authorware programme. Many functional modules are becoming easy to be organized and controlled through being linked by the next framework icon. Obviously, realizing the role and the status of framework icon is very important.
