batch file to read specific letters from a text file?

Question

Hi, I have a txt file called named.txt Is there a way to create a batch file to read every letters 2 through 7 letters from every line from name.txt and ignore the rest and output it onto a different txt file called name2.txt. For example I have this in the txt file:

G2010060sample.png
G2010061sample.png
G2010062sample.png
G2010063sample.png

and the batch file would create a new txt file like this :

2010060.png
2010061.png
2010062.png
2010063.png

Excellent online ressource http://ss64.com/nt/syntax.html

@echo off
if exist output.txt del output.txt
for /f "delims=" %%i in (input.txt) do call :ParseLine %%i
goto :eof


:ParseLine
set line=%1
set line=%line:~1,7%
echo %line%.png>> output.txt
goto :eof
