+Attention: When the variable value contains the `\n` identifier, such as ` value = "hello \n world" `, value needs to be carried out in a special way. You need to use `print('${setValue(key=%s)}' % repr(value))`, otherwise the argument cannot be passed to the subsequent flow.

 #### Pass parameter from SubProcess task to downstream
 
 In the workflow definition of the subprocess, define `OUT` direction parameters as output parameters, and these parameters can be passed to the downstream tasks of the subprocess node.

+注意： 当变量 value 中含有 `\n` 标识，如 `value = "hello \n world"`， 则需要将 value 进行特殊进行，需要使用 `print('${setValue(key=%s)}' % repr(value))`, 否则参数无法传递到后面的流程。

 #### SubProcess 任务传递参数
 
 在子流程的工作流定义中定义方向是 OUT 的变量作为输出参数，可以将这些参数传递到子流程节点的下游任务。
