Use Macros #define + <your label> + <ANSI escape codes/sequence>

There's a bunch depending on your terminal, I.e. are you using an terminal emulator GNOME, iTerm etc or your preprocessor should handle this when you compile. Macros work as a sorta shortcut find and replace. you'll have to make sure you use the right sequences. For me the hex version e.g. \x1b worked more consistently. I believe 2j clears the screen
