Just rephrasing what John said, in my own words and view: An emulation typically adds an this/self instance reference to the parameter list of every method. "Real" OO languages simply hide this parameter in the source code, i.e. the compiler changes the parameter list and calls accordingly. That's what your translator should add to the translated source code. That's all about basic (static) methods. Instance data is a record (struct...), containing all data fields of the class. BTW the first C++ compiler was such a translator, from C++ to C. I don't remember its name, but it should be available in the museum - John?
