This machine will encode/decode your username or a word! Press E to encode (Type whatever, but if you want to encode your username, type "UN"), and D to decode. You can encode as many words or phrases(including "UN"[your username]) as you want, and after pressing D once, the decoding process will begin. Press D again to read the first thing that was encoded, and again for the next thing, and so on. Once it's done, the encoded will empty and you can encode whatever again! This is VERY useful if you wish to store usernames or other letter-based strings on the Cloud. Encoding the word turns it into numbers, so that it may be stored on the Cloud. Decoding the encoded word turns it from numbers to letters, so that you may retrieve it from the Cloud and read it.
Credit to TheSurfingScratcher for showing the basic idea (not including the multi-string code) and credit to Scratch for the laptop. The laptop sprite is the sprite holding the information and code, so don't delete it. If you want to use this Encoder/Decoder, make sure to give credit where it's due! 80+ blocks divided into 5 scripts all inside 1 sprite Code could be moved to the backdrop making use of the backpack if you wish.
