Re^2: What I am missing here

Hmm.. so it`s just a C-like error of mine. Sorry, I am still learning Perl, so I didn`t know that a special reference will be needed in the case. Well, thanks a lot, I`ll keep in mind that for the future.

I`ll look into references ( pointers ) asap when I finish the regexp part of perl, which I find a bit confusing. I guess pointers are as powerful as they were in C... I just had no idea there are any since Perl is garbage collected and, dunno... maybe I am a bit noob to this :)

Well, I would say that references are kind of a step up in terms of abstraction from pointers. For example, in C, you can point a pointer at pretty much any arbitrary space in memory; I don't think you can do that with references in Perl. I also don't think you could perform arithmetic on references (not that this is a great idea in C anyways). In my mind, Perl references are much simpler. They always point to a thing, and you just have to remember to dereference it to use the thing it's pointing to.	[reply]
