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
复制代码

@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!"
for /l %%i in () do if defined  !e! (call set e=%%!e!%%) else echo !e!&pause&exit
