Is that interface still preserved in the modern Blackbox on Windows? Found this great presentation on both it and all the concepts it uses for robustness:<p><a href="http:&#x2F;&#x2F;www.pas.rochester.edu&#x2F;~skulski&#x2F;Presentations&#x2F;BB_Class.pdf" rel="nofollow">http:&#x2F;&#x2F;www.pas.rochester.edu&#x2F;~skulski&#x2F;Presentations&#x2F;BB_Class...</a><p>I keep thinking I need to play with it as it looks to be a great tool. Like an engineer&#x27;s version of Visual Basic 6 I started on. Super easy to use, fast, and code-generating for GUI&#x27;s without huge issues of C development. The complexity chart was nice while showing good old ALGOL and Turbo Pascal 2.0 fit nicely in the middle. I think the Oberon&#x27;s are too simple but Component Pascal seems better.<p>Add Design-by-Contract and some more safety features to give Eiffel + Ada some nice competition in robust, OOP space. :)
