Thanks to all for your input. I consider this problem solved and I will write a little tutorial for those who might be interested. I now will be moving to another simple problem and will post the code here to go again with this process. In this way, we can accumulate slowly simple, but usefull problems resolved in a proper way. As I mentioned the idea is to have some sort of 99 problems for Smalltalk, of course everyone is invited to contribute. Best Nacho
