Oh, I'm still a beginner, all right :-)

Good enough.

% I would try to write it as
% while (<>) {
% my ($artist, $album, $track) = split m:/:;
% if ($track eq $foo) { # $foo eq "$foo" :-)
% ...
% }
% }
I don't see a difference here except that you're using a variable $foo
where I threw in a constant foo because it wasn't really important. If
the $track var in that example is undefined then it will throw an error,
right? So I don't see how writing it that way (aside from the nicer
split, which I'll also be doing in my next rewrite but at least I thought
of it before someone had to show me :-) will improve matters...

% I like fightings :-)
*grin*
% But to say the truth, it reads harder than I meant it.
% Of course, TMTWTDI, as I only wanted to say, it could be dangerous this way.
I understand, and I appreciate it.
%
% Again it was adressed to the many beginners outside the world.
% In fact, curiously, to understand why strict declarations and warnings are needed,
% it's more a problem to java beginners than to perl beginners.
% I still try to understand why :-)
Interesting. One more reason not to know java, I guess ;-) <ducks>
%
...
% > integrate single-case undef logic into the loop, no?
%
% Yep, you're right!
% (But taking my way would force every loop an undef, doesn't it :-))
True :-)
Hey, I could just undef *everything* between iterations and then I'd have
a higher probability of finding one, eh? :-)
%
% > I still don't quite get the whole "our"/"local" think yet. Still workin' on that.
%
% Oh, and I have always problems to explain it.
No problem; I'll get there.
Interesting... I just went to look for it in my 2e Camel book and can't
find it (only my and local). Hmmm...
% Well, when you'll understand the philosphy you never want to go back.

I imagine and I can't wait :-) I need to really "get" OOP, too.

Yay :-)

Good enough; one of these days I can lace up my boots and head off on a
rewrite then. As long as I'm not doing this flat-out incorrectly right
now it'll do.
%
% (It's like with doubled code which one is an alert signal for me too for various
reasons.)
Yeah. I already have some of that and am trying to work them out to a
single subroutine.
