Hi colorForthers,
Yesterday I had an idea about how to add ASCII/UTF-8 support to colorForth.
Today I wrote the code to do this, as a demonstration, and it works!!!
You can see the demonstration here : http://www.inventio.co.uk/cf2022/Encoding%20ASCII%20into%20cf2022%20colorForth%20tokens.pdf
I've been trying to do this for about 15 years, so I am very excited
that the idea just came to me yesterday.
In cf2022 colorForth, a Shannon-Fano encoded token consists of a 4 bit colour in the bottom four bits, and 28 bits of up to 7 letters.
For example, a white lower case comment "rrrrrrr" is
$11111119 , where '1' is a four bit code for the letter 'r', and '9' is
a white colour token. A sequence of Shannon-Fano letters can be
terminated by a 4-bit Shannon-Fano NULL, which displays as a space character.
The simple idea is that if the first Shannon-Fano encoded letter is a
NULL ( all four bits are 0 ) the token does not display anything (except
a space), so that in this case the remaining 24 bits can be interpreted
as three 8 bit ASCII/UTF-8 characters.
Now all I need to do is add ASCII/UTF-8 input, and support for international QWERTZ, AZERTY and QWERTY etc. keyboards...
Watch this space :-)

It could be that it needs https: https://www.inventio.co.uk/cf2022/Encoding%20ASCII%20into%20cf2022%20colorForth%20tokens.pdf
Or maybe funny line endings?

I've commented out the 'cmp' test - the ZR flag is set/unset by the preceding 'and'.
HTH!

Hi John(?),Fine.
Thanks - you are right!
I will update the code accordingly.
BTW Did you know that your name, placed in the reverse order, with a
comma, sounds like curmudgeon? I'm guessing yes.
