Thank you, zver and cajun72.
It´s good to have tips, help and other from you people.
When we start to find some aplication we know that must have a number of diferent programs, but only sharing experience we can learn, test and compare.
I hope you understand what I write, cause I don´t know much English. If I say something with no sense, please let me know.
By the way, Cajun72, the link you gave me is ok, except for the /CEP/, ok?
