Game Maker jak vyjádřit shodnost

Jak by v Game Makeru 8 měl vyjádřit shodnost: (místo ??? znak shodnosti )
var password, real_password,f;
password = get_string("Zadej Heslo:","");

f=file_text_open_read(working_directory+"\Password .txt");
//real_password = file_text_read_real(f);

//control es same
if password ??? file_text_read_real(f) {
game_end();
}
if !password ??? file_text_read_real(f) {
game_restart();
}
file_text_close(f);
