for loop in dos batch programming

Problem: I was wondering how a for loop would work in ms-dos batch programming and identified the following

solution: for /L %i in (,,) do command

for /L %i in (0,1,100) do echo %i%

perl libwww < 5.66

I had a terrible experience lately. I wanted to download a large document from a website and I opted to employ the content_file method. On versions of libwww < 5.66 I found that 'content_file'
$response = $browser->get("$url",':content_file' => $outfile);
Doesn't work as expected. An alternative method was identified Sean M. Burke where in one should use

HTTP::Request::Common;
$response = $ua->request( GET($url), $filespec );

which provides identical functionality but is compatible with older versions.
