I'm very grateful for the offert and, obviously, I accept it. If the java
program is small enought to be sended by mail, please send it at;
spir73[at]gmail[dot]com. I'll be very very grateful.
If it's a big file, If you send it for downloading, please type the link.
Thank you very much for your comments, both, Nicola and Santiago
