Hi, I am new at perl, using it for a month. It's a great language!

I need some help for threads, am trying to do threading but could not do that.

I have an script, which fetches data from internet, it's main structure is like this:

for ($i=0; $i<1000000; $i++) {

        $content = get("http://www.somewebsite.com/news.php?id=$i");
        print "Error!" unless defined $content;

... doing some trimming with regex ...

}

It actually does fetching more than 1000000 times. so, it takes long time. This is why i am trying to learn threads. I will use 10 threads.

However, I have $i value and am using it in the loop, so if I create 10 threads, it is doing same loop 10 times. I need something, which will do like;

for first thread :

http://www.somewebsite.com/news.php?id=1
http://www.somewebsite.com/news.php?id=11
http://www.somewebsite.com/news.php?id=21
http://www.somewebsite.com/news.php?id=31
...

for second thread

http://www.somewebsite.com/news.php?id=2
http://www.somewebsite.com/news.php?id=12
http://www.somewebsite.com/news.php?id=22
http://www.somewebsite.com/news.php?id=32

for third thread

http://www.somewebsite.com/news.php?id=3
http://www.somewebsite.com/news.php?id=13
http://www.somewebsite.com/news.php?id=23
http://www.somewebsite.com/news.php?id=33

.. and so on..

I have created 10 different sub routines and loops. Every loop is doing a part of fetching like;

first sub 1-100000
second sub 100000-200000
third sub 300000-400000

but it is not an elegant way of course. I would like to learn the correct format. i tried many things but could not success.

I also would like to change number of threads, so I guess, I also need to create a for loop for threads to do so. Then i can also change number of threads, but how?

Thanks from now on,
