The Boolean Node
The Boolean node () declares one or more named scalar Boolean variables that you can access from form objects and methods. You can use a Boolean variable as a source in check boxes, for example. The Settings window contains the following section.
List of Variables
This section contains a single table, where you specify one Boolean variable stored per row. Specify the name in the Name column and the initial value in the Initial value column (either true or false; the default is false). You can also add an optional description of the Boolean variable in the Description column.
Although you can specify the initial value for a Boolean variable, that value may be overwritten if you use the Boolean variable as a source to a form object that specifies a different value.
As a string, you can use on or off, true or false, or yes or no (all case insensitive) as Boolean values.
Use the Move Up (), Move Down (), Insert Above (), and Delete () toolbar buttons to organize and remove choices from the list.
Code Access
In the code of a method, you access a Boolean variable named bool1 as if it were a normal Java boolean variable:
boolean b = bool1;
bool1 = newValue;
