注意，启动页面必须与启动类型匹配，步骤页面必须与步骤类型匹配。

Note that the launch page must match the launch type, and the step page must match the step type.

在本例中，我用了三种Xproc步骤，步骤类型在工作流图中用矩形表示，如图2所示。

I used all three kinds of XProc steps in this example. Step types are represented as rectangles in the workflow diagram that Figure 2 shows.

您可以按照以上步骤寻找任何类型的资源：配置文件、审计文件、图形文件，等等。

You can follow this procedure for any kind of resource: configuration file, audio file, graphics file, you name it.

What we're saying is, in order to do computation, we want to describe recipes, we want to describe this sequence of steps built on some primitives, and we want to describe the flow of control that goes through those sequence of steps as we carry on So the last thing we need before we can start talking about real programming is, we need to describe those recipes.

我们在说，为了做计算，我们想描述一个方法，想描述建立在,相同基本类型上的步骤序列，而且我们想描述经过我们设计的,步骤的序列的，控制流程,因此我们开始谈论真正的编程之前,的最后一件事是，我们需要描述一下那些方法。
