## Scope
-The parameters defined on the process definition page can apply to all the scope of the process tasks.
+Global parameters are parameters that are valid for all task nodes of the entire workflow. It can be configured on the workflow definition page.
## Usage
-Usage of global parameters is: at the process define page, click the '+' beside the 'Set global' and fill in the key and value to save:
+The specific use method can be determined according to the actual production situation. This example uses a shell task to print out the date value of yesterday.

+### Create a Shell task
-
- 
-
+Create a shell task and enter `echo ${dt}` in the script content. In this case, dt is the global parameter we need to declare. As shown below:
-The `global_bizdate` parameter defined here can be referenced by local parameters of any other task node, and set the value of `global_bizdate` by referencing the system parameter `system.biz.date`.

+
+
+### Save the workflow and set global parameters
+
+You could follow this guide to set global parameter: On the workflow definition page, click the plus sign to the right of "Set Global", after filling in the variable name and value, then save it
+
+
+
+> Note: The dt parameter defined here can be referenced by the local parameters of any other node.
+
+### In task instance view execution result
+
+On the task instance page, you can check the log to verify the execution result of the task and determine whether the parameters are valid.

## 作用域
-在工作流定义页面配置的参数，作用于该工作流中全部的任务
+全局参数是指针对**整个工作流**的所有任务节点都有效的参数，在工作流定义页面配置。
## 使用方式
-全局参数配置方式如下：在工作流定义页面，点击“设置全局”右边的加号，填写对应的变量名称和对应的值，保存即可
+具体的使用方式可结合实际的生产情况而定，这里演示为使用 Shell 任务打印出前一天的日期。

+
+### 任务实例查看执行结果
+
+进入任务实例页面，可以通过查看日志，验证任务的执行结果，判断参数是否有效。
