这样数值会重复取吧

要求不重复取值可以这样：

@echo off
set n=15
set var=1234567890ABCDEFG
setlocal enabledelayedexpansion
for /l %%i in (1,1,9) do (
    set /a m=!random!%%n
    for %%j in (!m!) do (
        set str1=!var:~%%j,1!
        set str2=!str2!!str1!
    )
    set /a n-=1
    for %%k in (!str1!) do set var=!var:%%k=!
)
echo,!str2!
pause
