Command: !!

The !! command is intended to denote that what follows is written in the custom language. This script can be multiple lines long. For more information on programming, see the programming language documentation.

In addition, there is also a !< command. Using !< instead of !! causes the system to process the input into a set of tokens and then send the token list back to you instead of executing them. For advanced programs this is likely to run afoul of the 2,000 character limit. It is a good way to debug very simple programs though to see what the system thinks that you wrote and how that compares to what you meant to write.
