Hello mgamar,

Welcome to the community, please read this link How (Not) To Ask A Question and this How do I post a question effectively?.

By writing an effective question, it attracts interest of more people to help you solve your problem. Upload your code, show to the people what you have tried so far and where you have failed.

Not everyone is familiar with your problem, but we are willing to read and make an effort to help with your problem. Just by writing:

Could somebody tell me how manage the variables, o give me some tip to start this.

It is impossible to actually know what is your problem, and how to solve it. Provide us with a sample of your file and with a sample of the desired output that you have in your mind.

I hope my answer did not confuse you but helped you.

Seeking for Perl wisdom...on the process of learning...not there...yet!
