不提倡生成临时文件，批处理可以自身修改密码的。

请高手精简一下~或者指点一下如何不生成临时文件？

@echo off 

set code=abcdefghijklmnopqrstuvwxyz0123456789-_

for /f "tokens=2" %%i in (%~nx0) do set passwords=%%i

:begin

set /a n=%random%%%38,m+=1

call,set pwd=%pwd%%%code:~%n%,1%%

if %m% lss 16 goto begin

echo.:: %pwd%>>%~nx0

cls

set /p password=请输入密码：

if "%password%"=="%passwords%" goto ok

cls

echo 密码错误&ping /n 2 127.1>nul&goto begin

pause&goto :eof

:ok

echo 密码正确！&pause&goto :eof

:: abcdefghijklmnop
