Conditional on or off properties

A conditional on or off property tests to see if a condition has been met. It is on if the condition is met, off if the condition is not met. There is no middle ground. Use Boolean formulas for this kind of formatting.

Basic syntax example

formula = condition

The program tests each value to see if it meets the condition and it returns a "yes" or "no" answer. It then applies the property to every value that returns a "yes" answer.
