My plan is to simply have the editor syntax highlight the built-in words in
various (configurable) ways. Comments, for instance, () and \ would be
highlighter in a certain way. Numbers in another. Standard Forth words
that are not simple symbols in another way. Forth words like + * . : ;
(etc) would be highlighted in another way. RCX-specific words in pbForth
would be highlighted in yet another way. All of this would be user
configurable. I may also have a user-definable category of words to syntax
highlight.
I uploaded a JPG to my website that shows my preliminary work:

FALSE, TRUE, HEX, PICK, and U> are all listed in the CORE-EXT section of the
PDF I looked at and Ralph Hempel lists them among the words he discusses in
his 1999 "Introduction to pbForth" so that's why I wonder.
Thanks,
