Ok, no problem. Worked for me here but then copy/pasted wrong version, line 19 should have been
echo %%i=!value!
Steve
echo %%i=!value!

Thanks for all of your rely.
I tried obda 's code in one time, it works as I expect
and dragon-it, thanks for your code, I tried it that seems not working
even review it many times and check all correct file typing and path.
The output junk.txt is same as before
Thanks for your attached link for the subject
Have a nice

I read there that you wanted "+" in the results, if not just remove the "+" characters.

Try this. Few problems in there including within a single command like the for command you can't access variables set like your str entry unless you have delayedexpansion turned on (see line 2). Then you use !variable! to access.

Other alternatives are to use a util. to do it for you, e.g.

Try it with this script; it will make a backup of the original file before changing the original:
@echo offsetlocal enabledelayedexpansionset InputFile=C:Tempjunk.txtset NewHostName=203.1.123.342set NewPort=00001779set BackupFile=%InputFile%.bakif not exist "%BackupFile%" copy "%InputFile%" "%BackupFile%" >NULif exist "%InputFile%" del "%InputFile%"for /f "tokens=1-3 delims==:" %%a in ('type "%BackupFile%"') do ( if "%%~c"=="" (set Line=%%a=%%b) else (set Line=%%a=%%b:%%c) if "%%~a"=="HostName" (set Line=%%a="%NewHostName%") if "%%~a"=="PortNumber" (set Line=%%a=%%b:%NewPort%) echo !Line! >>"%InputFile%" echo !Line!) 1:2:3:4:5:6:7:8:9:10:11:12:13:14:15:
