Example of use 

Task

There is a "Logical variable 1" with value = true and "Logical variable 2" with value = false. It is required to check the expression Logical variable 1=True OR Logical variable 2=True.  If the result is positive, display a dialog box with a message - true, if the result is negative, the message is false. 

Solution

Use the actions "Excluding disjunction", "If", "Show message". 

Implementation 

  1. Assemble a robot scheme consisting of actions: 


  2. Create a variable with type logical "Logical variable 3" to record the result of action "Exclusive disjunction" into it. 
  3. Move the "Exclusive disjunction" action to the workspace and set its parameters
  4. Move the "If" action to the workspace and set the action parameter to "Logical variable 3". 
  5. In the "True" branch, add the "Show message" action and set its parameters.
  6. In the "False" branch, add the "Show message" action and set its parameters.
  7. Start the robot using the "Start" button and the top panel. 

Result 

The comparison of variable values has been performed successfully.


A dialog box with the result is displayed.
