Show HN: R3forth, a ColorForth-inspired language with a tiny VM

In the first code example in the readme ("First program"), there's `sdlcls`, `SDLinit`, and `SDLShow`. Is there some significance to the capitalisation?

Very impressive demos! I did a quick look through the docs- it’s single threaded (in the cpu sense) and not multi process yes?

Very nice graphics using SDL2!

So many features-- sprite sheets, etc. Well done!

Very interesting, great work! This reminded me of something. I just checked and to my amazement Mike Hore's Powermops is still around and even has an ARM version.[1]
