Thanks for the review. Sounds like it's what I used to call an "industrial" BASIC where it has the features and compiler to get real work done. Many people think some toy with a few key words and interpretation when they think BASIC. Yet, I used to do all my hacking in it and Visual Basic 6 for GUI layer. Loved VB6 specifically for rapid iteration: instant load, instant test-run, instant... you name it on P3 400Mhz w/ 128MB RAM.
That efficiency on arbitrary hardware is something industrial BASIC's and Wirth languages have in common. Only Go can touch it these days but still not low-level as Wirth stuff gets.
Yes, I would agree with "industrial", especially since you can link with any C library after translating the headers with SWIG (translations of common libraries like C, winapi and GTK are included with FB). I've never used/don't know VB, but it appears that quite a lot of FB's design is borrowed from it. In recent years FB has been focused on borrowing C++ features instead (and even aiming to be ABI compatible with g++, not sure if that works). E.g. recently added "dim byref" (like a C++ reference variable) and polymorphism + RTTI. Sometimes things move in the other direction, like binary literals new in C++14 :)
