The Chord Tool Example database demonstrates how 4D objects can be shown or hidden based on the value of a long integer. Using bitwise operators, we can assign an offset (the Key) and then a definition of what bits (Notes) are used in the chord. We show the objects if the bits are True, and hide them if they are False.

The tech note also includes an invaluable history lesson on the origins of "Arabic" numerals and the words algebra and algorithm.
