Question

我正在尝试使用批处理脚本编写一个基本的琐事游戏，以便在我的笔记本电脑上的DOS CMD中运行。这只是一个实验性的事情，所以我可以练习使用批处理脚本。

第一个问题将在没有问题的情况下执行，但我无法执行第二个问题。它继续说，＆＃34;在这个时候意外发现＆＃34;。为了解决这个问题，有什么我需要注意的吗？

感谢您的协助。

Answer 1

你的错是一次有一个带有var名称的尾随空格 set /p ScotlandAnimal = choice1~3
和内容，然后检查没有该尾随空格的var名称 if %ScotlandAnimal%==1 goto incorrect
由于没有空间的var不存在，因此它的计算结果为空，因此cmd解释器看到了
if ==1 goto incorrect
这是无效的语法。

Answer 2

将set /p更改为Choice并更改结构，以便您不需要多个goto包含相同/类似输出文本的标签，就可以提供更好的服务。< / p>
