Boolean data type
A Boolean is a primitive data type that can have one of two values: True or False. It is represented by green wires on the block diagram. The Boolean constant is represented by a dynamic element that can be changed from True 
to False 
with a left mouse click.
Most functions from the Comparison palette return Boolean values.
History
In LabVIEW 2010 the representation of Boolean constants on the block diagram changed so that only the currently selected value is visible.
