Dear friend:
Thanks a lot by your suggestions :). I made this code at the beggining of my perl efforts and I hadnīt open It until I pasted It on the post, and of course the code was very simple :) I can see that your is much better.
I'm just going to buy on the net the 3rd edition of the programming perl (because it hasn't arrived to the Spanish market by now) to have a better knowledge of the programming language :) the problem is that I'm totally self-teached on computer sciences (I program on VB C and now Perl but learning on my own way, buying books, downloading tutorials, etc) and I advance too slow sometimes, I suppose that with that reference book I'll learn better 'programming skills' from now on ;)
Best regards
