@echo off&setlocal enabledelayedexpansion
set "a=bathome"
::以下for循环实现的是set "b=a"&set "c=b"&set "d=c"&set "e=d"
for %%a in (ba cb dc ed) do set "str=%%a"&set "!str:~,1!=!str:~1!"
call call call call set /p=e=%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%e%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

发现这样还简洁点，请问各位前辈，还能再简洁不了呢。。。

@echo off&setlocal enabledelayedexpansion
set "a=bathome"
::以下for循环实现的是set "b=a"&set "c=b"&set "d=c"&set "e=d"
for %%a in (ba cb dc ed) do set "str=%%a"&set "!str:~,1!=!str:~1!"
call call call set /p=e=%%%%%%%%%%%%%%!%e%!%%%%%%%%%%%%%%
pause

请问terse前辈为什么不这样写呢？

@echo off&setlocal enabledelayedexpansion
set "a=bathome"
set "b=a"&set "c=b"&set "d=c"&set "e=d"
for %%i in (b c d) do for %%j in (!%%i!) do set %%i=!%%j!
echo !%e%! 
pause
