# Retro/Napia Words
|
|
|
|
This adds support for some words from Retro/Napia. It's intended
|
|
to aid in portability between the systems.
|
|
|
|
The basic math operations are given non-symbolic names and
|
|
placed in the `n:` namespace. (In Retro/Napia, these are the
|
|
standard names for these).
