我正在尝试针对特定情况生成多个文件，但我的循环语句无法正常工作。 批处理文件有三个条目，例如：
Unit code = e.g (095)
Initial date = e.g (20211001)
Final date = e.g (20211010)
我期待 10 个文件，像这样。因为从初始日期到最终日期我们有 10 天，在本例中，但也可能是 15、20...
2v09520211001.rep
2v09520211002.rep
2v09520211003.rep
2v09520211004.rep

提前谢谢您。
这是一个完整的代码，用于从文本文件中读取数据或提示批处理文件的用户输入数据，并在使用字符串创建具有适当文件名的空文件之前验证字符串。

使用 PowerShell 来完成此任务会更好。 PowerShell 支持使用正则表达式进行内置字符串验证，还支持通过日期计算本机处理日期，而 Windows 命令处理器 CMD 根本不支持。
