Example

This program will count as high as you like when you press button A. When you get tired of counting, press button B to reset the @boardname@ and start the program over.

let item = 0;
basic.showNumber(item);
input.onButtonEvent(Button.A, input.buttonEventValue(ButtonEvent.Down), () => {
    item = item + 1;
    basic.showNumber(item);
});
input.onButtonEvent(Button.B, input.buttonEventValue(ButtonEvent.Down), () => {
    control.reset();
});
