I need to find and insert a value - batch-file

Question

I'm writing a script that needs to find a numerical values or digits in a text file and replace it with input from my keyboard.
I have searched on the internet and just can't find the correct way to do it.
The text file contains the following:
C:\Progra~1\Java\userapp\fundays\jv10_80cl1\test
i need to change the "80cl1" part to new values eg: 80cl1 changes to 84cl3
:begin1
setlocal ENABLEEXTENSIONS
setlocal ENABLEDELAYEDEXPANSION
SET /P E= new value 1:
FOR /F "tokens=1 delims=:" %%a in (install.txt) do findstr /r "^[1-9][0-9]*$"
echo "%%a"
SET /P R= New value 2:
FOR /F "tokens=1 delims=:" %%a in (install.txt) do findstr /r "^[1-9][0-9]*$"
echo "%%a"
So, the script needs to find those values and change it via keyboard input.

Something like this should help. You can change the set /p to not promp and just give it a value, either way will work:
#echo off
setlocal enabledelayedexpansion
set inputfile=install.txt
set /p "_strfind=Enter value to search?"
set /p "_strinsert=Replacement value?"
for /f "tokens=*" %%a in ('type "%inputfile%" ^| find /v /n "" ^& break ^> "%inputfile%"') do (
set "str=%%a"
set "str=!str:%_strfind%=%_strinsert%!"
set "str=!str:*]=!"
>>%inputfile% echo(!str!
)
If you do not want to be pompted, just set the values before hand:
#echo off
setlocal enabledelayedexpansion
set inputfile=install.txt
set "_strfind=80cl1"
set "_strinsert=84cl3"
for /f "tokens=*" %%a in ('type "%inputfile%" ^| find /v /n "" ^& break ^> "%inputfile%"') do (
set "str=%%a"
set "str=!str:%_strfind%=%_strinsert%!"
set "str=!str:*]=!"
>>%inputfile% echo(!str!
)
If by any chance your file might contain ! it will not replicate them to file, then simply use this:
#echo off
set "inputfile=ip.txt"
set /p "_strfind=string to replace?"
set /p "_strinsert=replacement string?"
for /f "tokens=*" %%a in ('type "%inputfile%" ^| find /v /n "" ^& break ^> "%inputfile%"') do (
set "str=%%a"
setlocal enabledelayedexpansion
set "str=!str:%_strfind%=%_strinsert%!"
call set "str=%%str:*]=%%"
>>%inputfile% echo(!str!
endlocal
)
Edit, as per your comment:
#echo off
set "inputfile=install.txt"
set /p "_strfind=string to replace? "
set /p "_strinsert=replacement string? "
set /p "_strfind2=enter Executable numeric value to replace? "
set /p "_strinsert2=enter the replacement value for executable? "
set "_strfind2=%_strfind2%.exe"
set "_strinsert2=%_strinsert2%.exe"
for /f "tokens=*" %%a in ('type "%inputfile%" ^| find /v /n "" ^& break ^> "%inputfile%"') do (
set "str=%%a"
setlocal enabledelayedexpansion
set "str=!str:%_strfind%=%_strinsert%!"
set "str=!str:%_strfind2%=%_strinsert2%!"
call set "str=%%str:*]=%%"
>>%inputfile% echo(!str!
endlocal
)
