Extend your answer to the previous problem by adding a “clone” button. Pushing this button should create an additional window containing another counter. This will, of course, require additional threads. Explore the details of subroutine calls in the GNU Ada translator gnat. Pay particular attention to the more complex language features, including declarations in nested blocks (Section 3.3.2), dynamic-size arrays (Section 8.2.2), in/out parameters (Section 9.3.1), optional and named parameters (Section 9.3.3), generic subroutines (Section 7.3.1), exceptions (Section 9.4), and concurrency (“Launch-at-Elaboration,” Section 13.2.3).
