// Runs an infinite loop that listens to the keyboard input.
// When a key is pressed (any key), the program blackens the screen,
// i.e. writes "black" in every pixel. When no key is pressed,

// File name: projects/4/fill/FillAutomatic
// This script can be used to test the Fill program automatically,
// rather than interactively. Specifically, the script sets the keyboard
// memory map (RAM[24576]) to 0, 1, and then again to 0. This simulates the
// acts of leaving the keyboard untouched, pressing some key, and then releasing
// the key. After each one of these simulated events, the script outputs the values
// of some selected registers from the screen memory map (RAM[16384]-RAM[24576]).
// This is done in order to test that these registers are set to 000...0 or 111....1,
// as mandated by how the Fill program should react to the keyboard events.
