Scratch! How each block works: - create variable () - creates a variable, if it doesn't already exist or it isn't blank. - set () to () - Sets the variable, if it exists, to the specified value. - change () by () - Changes the variable, if it exists, to by specified value. - delete variable () - Deletes the variable if it exists.
