//addWithWhile.txt
x0 = x2; // this is a comment
WHILE x1 != 0 DO
x0 = x0 +1;
x1 = x1 - 1;
END
```
```
//mulWithLoop.txt
z1 = x1;
z2 = x2;
x0 = 0;
y0 = 1;
LOOP z2 DO
    x1 = z1;
    x2 = y0 - 1;
    x3 = x0;
    y10 = y0;
    z11 = x1;
    z12 = x3;
    x0 = x1;
    y0 = 1;
    LOOP z12 DO
        x1 = z11;
        x2 = y0 - 1;
        x3 = x0;
        x0 = x3 + 1;
        y0 = y0 + 1;
