考虑后如下，但效率低

@echo off&setlocal enabledelayedexpansion
:jj
set aa=1 &set "bb="
for %%i in (a b c d e f g h i j k l m n o p q r s t u v w x y z) do (
set !aa!=%%i &set /a aa=!aa!+1
) 
set va=1
:tj
set /a dd=%random%%%26+1 &set/a ss=%random%%%2
echo %bb% |find "%dd: =%">nul 2>nul &&goto tj
set bb=%bb% %dd%
if %ss%==1 (set/p=%dd% <nul) else set/p=!%dd%! <nul
set/a va+=1
if %va% lss 11 goto tj

请问 set_ 是什么意思？还有那个 set "_!random!!random!!random!=%%i 呢？
