I agree.  I based my code upon how Chuck defined his 'logo' word, so maybe you
should ask him.  :-)

There is another word, 'string', that is used in some of the other blocks.  It
appears to be the Right Way to do this, along with a TYPE-like word, but it
isn't working out for me yet.

The current colorForth doesn't provide any easy way to write "parsing words",
as far as I can tell.  Maybe if someone could create a simple example of how to
unpack characters, it would be helpful.

Everyone is welcome to use my wiki.  Edit the pages, add new pages, upload
files, whatever.  It is currently focused on Quartus Forth, but if there is
sufficient interest, I wouldn't mind creating a ColorForth subwiki.
