Why not using "ModalConfirm(confirmMessage, buttonList)"? From the Newton Programmer's Reference (pg. 2-32), here's the relevant doc:

"This method creates and displays a slip that returns the result of the userís
choice. Because this method causes a new task to be spawned, it is less
efficient and takes more system overhead, so you should use
AsyncConfirm in most cases."

As the doc recommends, you could use "AsyncConfirm", but this method immediately returns execution to the NewtonScript code that called it. Since you're looking for a real confirmation,
it might be easier to put up this modal so that your code resumes only once the user has made his choice. Depending on what you're doing, it might be easier. However, if you could
handle that reply asynchronously, then you should use "AsyncConfirm", which takes one more argument, a method to call that takes one argument, the result of the user's choice.

HTH!
