You can’t, because the reason the code exists is because you need its formality in order to eliminate ambiguity. Everytime code is explained without showing the code, there’s a baseline of understanding that’s required to filter the additional ambiguity. The only approach left is to refer to the domain. As the person is familiar with it, you illustrate the behavior that is currently programmed by the system. The program itself should be a blackbox. Only knobs and sliders should be left (aka any professional software).
