cantDelete

 set [the] cantDelete of card ¬
    to trueOrFalse
set [the] cantDelete of bkgnd ¬
    to trueOrFalse
set [the] cantDelete of stack ¬
    to trueOrFalse

The cantDelete property returns or sets whether a user can delete a specified card, background, or stack. It corresponds to the Can’t Delete check box in the Card Info, Background Info, and Protect Stack dialog boxes.

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

Note: Setting the cantDelete of a stack to true doesn't prevent the user from deleting the stack by dragging it to the Trash.
