输出1个 16位滴数字..必须符合
set tm5=%date:~2,2%
set tm6=%date:~5,2%
set tm7=%date:~8,2%
set yzm=%random:~-1%
set /p yzm=
pw=%yzm:~2,2%%yzm:~9,2%%yzm:~4,2%
同时pk=%tm5%%tm7%%tm6%
%pw%=%pk%
yzm =多少? 位数为16位 随机数.但要符合上面条件

%random%和%date%每次都会被动态计算

是不是这样？
set tm5=%date:~2,2%
set tm6=%date:~5,2%
set tm7=%date:~8,2%
set ran=%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%
set yzm=%ran:~,2%%tm5%%tm6%%ran:~,2,3%%tm7%%ran:~5,5%

set tm5=%date:~2,2%

set ran=%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%%random%
set yzm=%ran:~,2%%tm5%%tm6%%ran:~,2,3%%tm7%%ran:~5,5%
echo %yzm%
这一行：set yzm=%ran:~,2%%tm5%%tm6%%ran:~,2,3%%tm7%%ran:~5,5%
多打了一个,
应该是：set yzm=%ran:~,2%%tm5%%tm6%%ran:~2,3%%tm7%%ran:~5,5%
既然通过截取%date%已经指定了16位中的6位，那么使用10个%random%就足够了，不需要11个。。。<img src="images/smilies/face-raspberry.png" align="absmiddle" border="0"><img src="images/smilies/face-raspberry.png" align="absmiddle" border="0"><img src="images/smilies/face-raspberry.png" align="absmiddle" border="0"><img src="images/smilies/face-raspberry.png" align="absmiddle" border="0"><img src="images/smilies/face-raspberry.png" align="absmiddle" border="0"><img src="images/smilies/face-raspberry.png" align="absmiddle" border="0"><img src="images/smilies/face-raspberry.png" align="absmiddle" border="0"><img src="images/smilies/face-raspberry.png" align="absmiddle" border="0">

楼主，不要简单的问题复杂化，那么问题就简单了
