How do you do undo in logo?

Answer 1

In Logo, you can use the UNDO command to reverse the last action taken in your drawing. Simply type UNDO in the command line to remove the most recent change. If you want to restore something that was undone, you can typically do so by issuing the REDO command, if supported by your Logo interpreter. Always check your specific Logo environment's documentation, as commands can vary slightly between versions.

Answer 2

In Logo programming, the "undo" command isn't a built-in feature like in some other programming environments. However, you can simulate an undo by keeping track of your previous commands or using a list to store your actions. If you want to revert to a previous state, you can manually re-enter the commands that would restore the desired state. Alternatively, you can use procedures to define actions and manage states more effectively.
