Possibly the quickest way Argentine institutions will provide 'web services'

LOL, unfortunately true. At very least I'm glad they're using plain old HTML rather than Flash or some other nonsense.

That is really useful! :)
Maybe here in Brazil we could also use this kind of web services hehe :)

Haha, I would just be happy if Brazilian web forms stopped asking people in other countries for a valid CEP! I can't tell you how many times I've had to Google for the format to defeat crappy form validation.

hahaha yeah, that is true! :)
But i think that is some kind of global issue, i can't remember how many times i had to find myself a zip code as well hehe

Tanto más rápido que usando el sitio, gracias Norman! :-)

Al final lo actualizaron y la interfaz web vuelve a ser fácil. Me di cuenta porque el código dejó de andar, bienvenida la renovación!

Excelente - en un mundo ideal no existirían estos gists. :)
