Details of Repeated Task 2

Say that Repeated Task 2 can be implemented as a two-way choice. Now the design looks like:

Initial Task

DO WHILE not yet done
  'Repeated Task
  Repeated Task 1

  IF test-between-choices THEN
    Repeated Task 2A
  ELSE
    Repeated Task 2B
  END IF

  Repeated Task 3

LOOP

' Final Task
IF test-between-choices THEN
  Final Task A
ELSE
  Final Task B
END IF

END
