#847. Sending a message

when green flag clicked
set [x v] to (7)
broadcast [double v] and wait
change [x v] by (5)
say (x)

when I receive [double v]
set [x v] to ((x) * (2))

def double():  # when I receive [double]
    global x
    x = x * 2


# When the green flag is clicked
x = 7
double()
x += 5
print(x)

let x = 0;

// when I receive [double]
function double() {
  x = x * 2;
}

// When the green flag is clicked
x = 7;
double();
x += 5;
console.log(x);
