Clear is a built-in program in ComputerCraft. You may want to use it in a script like:
shell.run('clear') print('Your screen has been cleared!')
or just type:
in the computer.
This clears the screen so you can write text.
NOTE: It is not recommended to use the above code in a program, instead use Term.clear. It is only recommended to use this program to clear the screen through the shell.
