True/False
by REAS <http://reas.com>

Boolean data is one bit of information. True or false. It is common to use Booleans with control statements to determine the flow of a program. In this example, when the boolean value "x" is true, vertical black lines are drawn and when the boolean value "x" is false, horizontal gray lines are drawn
