Guten Tag

Actually I am not Deutsche, just living here.

Sorry, I shouldnt have raised your hopes so high. There isn't really a CDR module (that I know of), basically because there are a lot of different kinds of CDR. For different switches and the like. For instance I know of at least three or four kinds just where I work.
No the module I was refering to is called Tie::Hash::Trie and will be uploaded to CPAN by the end of the weekend and it has some properties that you might find useful if you are dealing with CDRs. I will let you know when it has be uploaded. (sorry, for the lack of details, but im in the middle of writing the pod and dont want to have to do it twice. :-)

What I don't know is why when you can write something so simple that most of you give me this highly complex code atleast from my point of view you guys are used to it

I can sympathize but I wont agree. You see usually a 'simple' solution provides simple results, this means it may work for a limited set of cases but meltsdown when the going gets tuff. (Good example are Godzilla!'s posts on CLPM, usually they work for the problem at hand but really are not viable for long term scenarios)
The more complex solutions, while a little harder to understand are usually much more robust, scalable and frankly usually more usable.

I can understand that you dont want to use code that you dont understand, but I strongly suggest that you take the time to figure out the solutions that were posted. Also that you read those docs. Perhaps if you have access to a NT or w9x box have a look at the activestate distro? They have nice html pages of all the docs laid out in a very convienient form (similer to cpan.org etc) I have spent hours and hours and hours on those pages and still have more to learn.

Anyway, good luck, and sorry for the confusion, yves
