 - `I` Input: Outputs a marble with the next byte from the program input stream, if there are any
 - `0123456789` Digits: decimal digits are added to a marbles value after multiplying the marble with 10, this means that a marble passing over `123` would contain the number 123 afterwards. Digits are consumed by marbles passing over them.
