Adding u8 worked, thanks. As for CMD it was used only as a testing display, I don't need it in the actual app, and for testing I ended up writing to a file to see if it is working. And where I actually used it, it did worked.
After a long time not using C++, I picked it for a pet-project...
It works perfectly, but I have the feeling I use older solutions in my code, than those are available today. My code probably is pre C++11 (do we call it ANSI?)...
I'm looking for some reference material that can help me to learn the new and shiny things I may want to use in my code to make it faster, maintainable and readable...

How do you use a pointer to a function that is declared in the general scope within a class.
Do you pass the pointer as parameter to class function, save the pointer as a class member and then use the class member in a class function when needed?
Usually I don`t try to compile wild guesses. I did things as you would do with a pointer in my post above but often in c++ things that resemble in some places don`t have a syntax that matches everywhere.
Well, you should because:
1. Might take less time than waiting for an answer.
2. Compiler is never cranky or in a bad mood. At most it will issue an error message.
3. One wild guess leads to another and soon you end up with a nice brilliant idea
Mircea is quite correct, you should always try and build small samples. Apart from anything else, the error reports help you to learn. The compiler, linker and debugger excellent tools that aid in development. Had you started in the days when we had to submit a deck of punched cards and wait 24 hours for the compiler output to tell us one character was mistyped, you would appreciate how easy things are these days.
It`s interesting to hear where things started. I had my first computer experience in the 80`s on a computer with keyboard and a dedicated green and white screen (the screen was displaying only two colors). My first programming experience was on a computer that you had to connect to a TV set. It was a computer with 16 colors graphics.
Mine was the LEO* III in the 60s, second row first three pictures at Leo Computers Society. Leo 3 photos[^]. Most input was punched paper tape, and some punched cards, no mass storage, only magnetic tape.
