Tvbot's TV can be turned on and off with the "on" and "off" commands. Give it a try.
You can also change the channel on Tvbot's TV. You do this by giving Tvbot the "channel" command, and putting a channel number between the two brackets. Tvbot can be tuned to channels 0, 1, 2, 3, or 4.
Sometimes you can give a command directly to the computer. In these cases, you don't need to type an object or the period. You just type the command only. One of these commands is "show." The show command will show a number on the screen. If you put a number in-between the brackets, that number will be shown on the screen.
