Example of current batch file: Line1 Line2 Line3 Line4 MY PROG NAME=%PROGNAME% Line6 Line7 SET THIS IS IT= LINE9 MY PROG NAME= LINE11 I need my batch file to search the existing batch file and edit the "MY PROG NAME=" line to "MY PROG NAME=C:\Program Files..." The catch is their are two of the same entries. IE: MY PROG NAME=%PROGNAME% and MY PROG NAME= The second entry will always be on the same line in the batch file if that helps. **This is not the actual file but a lot shorter for example purposes** If any additional info is required please let me know.

@echo off & setLocal EnableDelayedExpansion > newfile for /f "tokens=* delims= " %%a in (my.bat) do ( set /a N+=1 if !N! equ 10 ( echo MY PROG NAME=C:\Program Files... >> newfile ) else ( echo %%a >> newfile ) ) ===================================== If at first you don't succeed, you're about average.

Worked like a charm. Thanks for your help.
