swap_slots

-- Use this script to swap the contents (key and element) of two slots in the catalgoue
-- requires 20.000 BLOCKS v2.5 with the new horizontal layout

-- HOW TO USE
-- You need two people in the world to be able to do this:
-- 1. go to the catalogue and note down the numbers of the two slots you want to swap
-- 2. go to the computer and open it
-- 3. type "swap_slots <number_of_slot_1> <number_of_slot_2>"
-- 4. press ENTER and wait a bit
-- 5. if all goes well it will output "success""
