There is no way to dynamically resize stack. You need to assign an amount that is large enough when you start the task.

(Also, you posted your question as the response in another topic; I split it into its own topic for you.)

Can you not post questions that have nothing to do with eachother in the same topic? It all but guarantees you won't get an answer, as the people who can answer the later questions won't click on your topic.
