Example
We are keeping track of the last 5 roulette numbers in a data record spin list. We only want to keep track of the last 5 numbers that have appeared. When the data record spin list has more than 5 items in the layout list, we will use the Move List Up and shift the items to the left by 1 and set the Layout index to the maximum number of items. The next time a number appears, it will be appended to the last position of the data record. The following example will perform this task.
