我的批处理代码有一些问题。无法找出为什么它会因为括号而抛出错误

Question

自己拿代码检查一下，每次它都能问我开始时间，然后是上午还是下午，但只要我点击进入 am/pm，它立即关闭，我在关闭时截图了，它说( was unexpected here。如果有人可以帮忙，那就太好了。（此外，如果有人有修剪和优化技巧，那也很棒。谢谢）

你的问题出在这几行：

set /p 1ampm=[am/pm:]

和

if %1ampm% EQU %am% (

问题是变量名。 Batch 在调用批处理文件时可以获取参数，例如 %1 或 %2。这会导致批处理将其视为 %1 ampm % EQU % am%，但它没有参数，因此 %1 为空。之后它看到第一个百分号，看到它后面没有数字，并将其视为名为 % EQU % 的变量的开头，该变量也是空的。然后，它删除最后一个百分号，只留下 ampmam ( 作为行。这就是引发错误的原因。

因此，要解决错误，只需使用数字以外的其他内容作为变量的开头。
