Logic Stage

When you click the Logic stage icon, you should see a dialog window as below.
For each logic rule, there will be at most three input conditions passing logic True or
False values to the Logic stage here. You can choose four logic operations by the
Type combo box: AND, OR, NAND, NOR. The logic operation will process the input
logic values, and generate a logic result value to the next Execution stage. After you
have selected the appropriate logic operation, click the OK button. The Logic stage
icon will change its pattern to present the current logic operation.
In order to present how the four logic operations work, we use the truth table to
describe. Here we take two input conditions as example. The letter "T" means logic
True, while the letter "F" means logic False.
