True/False Variables

A true/false variable is also known as a boolean variable.  This type of variable stores a true or false value.

For example, you might require users to enter their name at the beginning of an interaction.  Following that, you might create a true/false variable named COMPLETE and give it an initial value of false.  When the user enters their name, the COMPLETE variable sould be set to true.  When the user tries to continue from that page, a condition checks to see if the value of COMPLETE is true.  If so, the user is allowed to continue, but if COMPLETE is false, then they are prompted to enter their name before continuing.
