# New Words
|
|
|
|
This contains a variety of words from my more recent systems.
|
|
|
|
Notes:
|
|
|
|
`as:` is a new set of string words. These will be replacing the
|
|
existing set in the future. (In the current system, strings are
|
|
null terminated. The `as` strings are length-prefixed instead.)
