对于这个示例，使用数据流操作符输出端的蓝色箭头定义无条件连接。

For this example, define an unconditional connection using the blue arrow on the output port of the data flow operator.

较理想的做法是，字符串有一个如error或与之相似的子串(见蓝色粗体的语句)，这个子串允许测试者很快地在输出文件中查找到错误。

Ideally, the string of characters should have a substring such as error or something similar (see the statement in bold blue), which will allow the tester to quickly find the error in the output file.

为了将项目并行路由到两个流程片段(即用蓝色框住的区域)，modeler复制了Task 1的输出。

To route the items in parallel to two process fragments (visualized by the blue boxed areas), the modeler duplicated the outputs of Task 1.
