Many thanks for all the answers this is exactly what I was looking for! ...but be patient with me, I would like to understand what makes it work. These are the main points I don't fully get:

- how does the 'n n/A' know how many characters to take for the kategory and the counter. It would be easier to understand if it was something like 'n4 n4/A'.
- In the manpage I found that n is in "big-endian order". Do I have to change the code to use 'v' on a Sparc (Sun) maschine? Or is all that matters the data and not the maschine it is running on?
- I am not sure if I understand the line 'unpack(qq(x$offset x4 A$len), $data);' Is it correct that the two 'x' parameters are just there to consume some characters and only 'A$len' is really used?

Many, many thanks!
