样例程序17：MM_S17_Vis_ParseLabel
程序解读
以下为MM_S17_Vis_ParseLabel样例程序的代码及相关解释说明。
| 与MM_S1_Vis_Basic样例相比，本样例仅新增了解析标签的功能（加粗部分的代码）。因此，下文不再重复解释与MM_S1_Vis_Basic样例相同部分的代码（详情请参考MM_S1_Vis_Basic样例说明）。 |

END上述样例程序代码对应的流程如下图所示。
下表为解析标签的逻辑解读。用户单击指令名称的超链接便可查看该指令的详细说明。
| 流程 | 代码及说明 |
|---|---|
解析标签 |
MM_GET_POSE指令可以将某个视觉点的工具位姿、标签和末端工具编号分别转存至变量P071、I61和I62变量。本样例假设I061变量值为56。 通过上述赋值语句后，I064和I065的变量值为56。
因此，上述代码表示将I61解析成I064和I065（即56解析成5和6）。 |
根据解析后的标签值添加处理逻辑 |
上述代码表示，如果I064为5，则执行处理逻辑a；否则，执行处理逻辑b。用户可根据具体业务场景，针对不同的标签值，添加不同的处理逻辑。 |
