Batch Script Modification Needed

I have a script working great.  However the script and the 'filelist.txt' file will reside in:

C:\Scripts

While the data files in the 'filelist.txt' file will reside in

C:\Data

So the resulting files will also reside in:

C:\Data

Do I just put the whole path in the 'filelist.txt' file or do I need to change script?


@echo off
setlocal EnableDelayedExpansion

REM get a file name and the YEAR column
for /F "tokens=1,2 delims=|" %%A in (filelist.txt) do call :Extract %%A %%B

exit /b

:Extract FileName YearColNo
set filename=%1
set colno=%2

@echo Processing file %filename%

REM Get the header line
set head=
for /F "usebackq delims=" %%F in ("%filename%") do if not defined head set head=%%F

REM Construct RegEx for matching the correct year column
set pat=
for /L %%L in (2,1,%colno%) do set "pat=!pat![^^|]*|"
set "pat=^^!pat!2004^|"

> 2004_%filename%     echo,!head!
>>2004_%filename%     findstr /R "%pat%" %filename%
REM Head will be added automatically
REM > Non_2004_%filename% findstr /V /R "%pat%" %filename%

exit /b
