cantModify

 set [the] cantModify of stack ¬
     to trueOrFalse

The cantModify property returns or sets whether a stack can be changed in any way. It corresponds to the Can’t Modify check box in the Protect Stack dialog box.

Setting the cantModify of a stack to true selects both the Can’t Modify Stack check box and the Can’t Delete Stack check box in the Protect Stack dialog box. When cantModify is true, a padlock appears in the menu bar.

The default value is false (meaning that the card, background, or stack can be modified).
