Nice catch, but the SAVE function doesn't create cookies, what is created are session variables, which are lost when the browser is closed - unlike cookies, which can be configured to continue to exist even after the browser is closed.

@francisco use tag :SAVE(); as set cokei

It is used to get browser cookies, but I can't see no useful usage for it since there is no SETCOOKIE function.

An example usage is to create a cookie with Javascript and use the function to get the cookie created - but you could get the cookie with Javascript too, which makes the function useless.
