How would you convert a message into numerical form using Cypher and loops.

It is unlikely you would do that, at least not directly.

If the message is an audio file or a movie, you would read the audio or video from the file; when you did that, then what you would have in memory would already be numerical form.

If the message is a string object or character vector, you would typically start by extracting the characters and using uint8() on them. If the string object or character vector could contain characters with position beyond 255, you would commonly use unicode2native, such as

unicode2native('say Ȣ','utf8')
