rem put me at the end of script
rem getting checksum for dlls
rem "goto :eof" here to avoid run this subroutine at the end of script, so script will run till this point, and sobroutine will called only where we need it
goto :eof
rem the subroutine itself starts here
:checksum
rem change the dir to first parameter, and remember it
pushd %1
rem now we are here, let's get the hashes for dll
for /F "tokens=1,2 delims= " %%a in ('%checksum% *.dll') do echo %1\%%a %%b >> %hashes%
rem return to the dir, where subroutine was called
popd
rem this is just for the case if another sobroutine will be after this one :)
goto :eof
