第一题：
@echo off
set i=今日明月在
set j=%i:~0,2%
echo %j%
set k=%i:~2,2%
echo %k%
set l=%i:~-1%
echo %l%
pause


第二题：
@echo off
set i=今日明月在
set j=%i:~2,2%
echo %j%
set k=%i:~0,2%
echo %k%
set l=%i:~-1%
echo %l%
pause

23楼改成如下会更好：

@echo off
set "str=今日明月在"
set/p =%str:~2,2%%str:~0,2%%str:~4,1%<nul
pause>nul
复制代码

五楼用call取延迟变量是错的！改成这样就好了！

set str=今日明月在&call ,echo %%str:~0,2%%&call,echo %%str:~2,2%%&call,echo %%str:~-1,1%%&pause
