为什么批处理前1-9的数据不能正常显示，但是10以后可以呢？

delab-1

我有一个文本数据，如下（在程序后）。我想让每个数据最后的第三列数据另存为一个文件，而且文件名以提取的第二个内容来命名（例如，com1.txt, com2,txt)。在每个文件中，让每个数据以列的数据排列。我编写下面的程序：

1. @echo off & chcp 65001 >nul
   
2. 
   
3. for /f "tokens=1,2* delims=," %%a in (example.txt) do (
   
4. (for %%i in (%%~c) do (
   
5. echo %%i))>%%b.txt
   
6. )

复制代码

但是上面的程序，仅仅转换出10以后得数据，但是1-9却不知为何转换不出来。有没有高手指点一下，哪里错了？

作为计算机小白，我也是第一次见，搜索了下，com是串口名称，不让用，换个名字吧。

com1,com2,...,com9 是系统保留字，不能被占用。改用以下代码即可...

1. 
   
2. @echo off &chcp 65001>nul
   
3. for /f "tokens=1-2* delims=," %%a in (example.txt) do (echo,%%c>"_%%b.txt")
   
4. pause&exit/b

太感谢了，随着用批处理越来越多，发现的问题也越来越多。太感谢了
