Emergency Stop Button

Robot C Graphical : is there a "stop all task"s in graphical for vex, we are trying to make a button that is an emergency stop. it is currently pretty laggy the way we have it written. Any suggestion how to write the code in graphical for an e-stop button?

ROBOTC graphical has a stopAllMotors block but, as there is no official way to create tasks, we do not have a stopAllTasks block. It looks like the community has given good advise on how to implement an emergency stop button here.

The general idea is to test the designated button each time around your primary while loop and take appropriate action.
