Getting the value of environment variables

["Luciano de Souza" <luchyanus@...>]

Hi listers,

How to know the value of a environment variable in Windows?

For example, %programfiles% stores the path where programs are usually installed. If I used Pascal, I would do this:

program env;

uses

dos;

begin

writeln(get('programfiles'));

end.

How to do the same in Lua?
