Line 19:
This task has no specific requirements to trap or correct cursor movement beyond the terminal boundaries, so the implementer should decide what behavior fits best in terms of the chosen language. Explanatory notes may be added to clarify how an out of bounds action would behave and the generation of error messages relating to an out of bounds cursor position is permitted.
