  likely, you had been referencing tw, the TurtleWindow instance from

  lc, the LogoCode instance, e.g., lc.tw. Now you can reference tw

  directly, e.g., tw. To reference lc, use tw.lc. Under most

  circumstances, Turtle Art will detect when myblock is looking for lc

  rather than tw and it will pass the correct argument.
