[文本处理] 批处理怎样查找显示字符串所在行和下面几行内容？

meiszp

有一个文本文件abc.st，文件内容很长，需要进行以下操作：
1.查找并显示出同时包含“ROTOT”和 "ROTORMASS"字符串所在行和下面4行内容，即：

ROTOT  ROTORLAENGE   ROTORMASS    WELLENMASSE  
   1          .4220       71.5872       55.3404
   2        3.8710   5913.1533    4718.9148
   3          .5050     162.4036         79.9331
TOTAL  4.7980     6174.1442   4854.1884


2. 提取红色数字进行下面计算，数据是变化的，但位置不变。
   
a=4*6500*71.5872/1500

b=4*6500*6174.1422/1500

求大神帮助，希望是bat代码。因为自己写了一些处理此文件的bat代码，想把他们组合。


问题补充：由于数据无法拷出，只能敲出部分内容，其他内容以图片形式提供。见网盘

最终想把提取的数据和计算显示在窗口。自己写了一个简单的代码，但有2个问题：
1.只能找出含有独一无二字符的行，即含有字符串的第1、2行和最后一行，数字行无法通过findstr寻找。
2.计算所需的71.5872和6174.1442不能自动获取，需要手动输入，bat会忽略小数点后的数据，因此只能输入整数，否则计算结果错误。

@echo off
findstr “ROTORMASS  (KG*M2) TOTAL”%~dp0\ljzs-in\abc.st
set /p N=N: 必须整数
set /p M=M: 必须整数
set /p MT=MT: 必须整数
set /a a=4*6350*%MT%/%N%
set /a b=4*6350*%M%/%N%
echo a= 4*6350*%MT%/%N%=%a%
echo b= 4*6350*%M%/%N%=%b%
pauseCOPY

网上找到一段使用findstr查找字符串所在行和下面一行内容的代码。此代码觉得可以借鉴，但不知道如何更改。

@Echo Off&Setlocal Enabledelayedexpansion
For /f "tokens=1* delims=:" %%i in ('Type a.txt^|Findstr /n "问问"') do (
Set n=&Set /a n=%%i+1

For /f "tokens=1* delims=:" %%a in ('Type a.txt^|Findstr /n "."') do (If %%a==!n! Echo %%b>>b.txt)
)

抱歉，我思路很乱，所以可能有不必要命令。
数不能太长，否则会计算失败。
文本内不要有特殊字符。如（&><?|等等

    你最终想得到的结果是啥

ivor

采用混编更快、更健壮、更简单，cmd+vbs or cmd+powershell

Perl 用户路过   

是只提取行标为1以及TOTAL 行的数据吗？
简化版：列标固定，行标采用匹配

use File::Slurp;
my @lines = read_file("abc.st");
my %rows = map { s/^\s+//; (split /\s+/, $_)[0,2] } @lines;
grep { printf "%s 4*6500*(%s)/1500 = %s\n", $_, $rows{$_}, 4*6500*$rows{$_}/1500 } qw(1 TOTAL);COPY

感觉会有一句话代码。

第二个计算出来会差几个百分点？

bat脚本混编powershell
就我这个最适合楼主需求了吧  ：）
