This programme emulates assumed machine F1.  It was done  by me when I had only conjectured about OOP or functional programming. And then, Pascal was only language that I had  known. So, don't judge me  strict.  Emulator is written in Pascal.  It might look simple and easy at first sight. If not: 

• here was done preprocessor from scratch(i.e. machine, according to requirements can read only binary code. But here was written preprocessor that gives you ability to write in "assembly" language commands. You can use mov,add,mul commands which will be replaced by binary code)
