Special conditions of use

The "If" condition can have only two branches. Each branch already has the result of the expression ("Yes"/"true") and "No"/"false") on which the transition to this branch will be performed. To add a sequence of actions to the branch body, you must move them to the outline of the corresponding action.

Example of use

Task
