要把值为0那一列都改成680-820之间的随机数，并在最下面求和。请问该如何编写批处理，谢谢！！
我想了很长时间，不得要领啊！

说两个问题：
1、论坛出现在线等啊，急啊之类的标题有被锁帖的危险
2、楼主你是污水处理厂的吧，我是你主管部门，告诉你们，你们年度考核不合格，连数据都给我造假  ：）开玩笑

给你个思路 先随即生成数字 然后替换 最后在相加
@echo off
:loop
set /a a=%random% %% 820
if %a% gtr 680 echo 随机数：%a%
goto loop 　
pause
替换：
@echo off
setlocal enabledelayedexpansion
for /f "tokens=* delims= " %%i in (3.txt) do (
set str=%%i
echo !str:00000=你所指的变量!>>结果.txt
)

tmplinshi

@echo off
set "File=a.txt"
SetLocal EnableDelayedExpansion
(for /f "usebackq delims=" %%a in ("%File%") do (
    if "%%~xa"==".000000" (
        set var=%%~na
        set /a n1 = 680 + !random! %% 141, Total_n1 += n1
        set /a n2 = 680 + !random! %% 141, Total_n2 += n2
        if "!var:~0,1!"=="," set /a n1 = Total_n1 - n1, n2 = Total_n2 - n2
        for %%b in (!n1!) do (
            set var=!var:,0.000000=,%%b.000000!
            echo !var:~0,-1!!n2!.000000
        )
    ) else echo %%a
)) > "%File%_.txt"
