批处理中的FOR和set问题

以下是我一个、bat文件里面的内容。大家看看，我的FOR 语句和SET之间是不是有什么不对。请给我指点一下，谢谢。

Answer 1

不好意思，我没把批处理看完。但我发现for语句的使用出了问题，如：
for /f "tokens=1,2,3,4 delism=."%%i (`spl%`) do set il1=%%i il2=%%j il3=%%k il4=%%l
应当是
for /f "usebackq tokens=1,2,3,4 delism=." %%i in (`"%spl%"`) do set il1=%%i il2=%%j il3=%%k il4=%%l
