Okay, so I've been lurking around for quite a while now, I just started a new job and need to learn Perl! So far, it seems quite wonderful. My question: I'm reading a friend's code and trying to understand how to open and write to a text file. I looked up how it is commonly done, and this seems different. 

 
open(DIN, "<$file_name");
    while (<DIN>)
    {
        next unless /(.*)Avg: (.*) V/;
        print OUT "$i, $2 \n";               
    }
    close(DIN);

sorry if my formatting isn't the greatest, I'm trying I promise! Also, what is "DIN" ?? Even google doesn't seem to be helping me there. thanks a ton <3
