    echo %letter%
    echo press a key to get a new letter
    pause
    goto a
    :a
    echo %letter%
    pause
    goto a

这是生成随机字母的快速方法。 %=ExitCodeAscii%包含的ASCII值%ERRORLEVEL%。 更多信息。

rem // generate a random number between 65 and 90
set /a "ascii = %random% * 26 / 32768 + 65"

rem // set errorlevel to that number
cmd /c exit /b %ascii%

rem // get letter corresponding to that exit code
echo %=ExitCodeAscii%
