WIP. Please report any bugs. Cloud data has been implemented! Don't make chat rooms. That's against the Scratch rules. Please don't hack the cloud either. Use turbo mode. This programming language uses postfix notation, so all functions go after their parameters. Input the whole program at once. New lines and indentation works. I recommend using Notepad++. There are error messages, but some things just break the program. Press § to stop the program. Example programs and a list of commands can be found at https://scratch.mit.edu/discuss/topic/340921/?page=1#post-3441477
