The 'mixing of interpreting & compiling' is confusing for me,
but colors work very well for me: to separate concerns.
So I'm keen to get rainbowforth running 'properly'.
[colorforth is tied to windows, so is no good for me.]

So far RF tests OK with eg:
 tst3 7 3 - . ;
 tst4 tst3 5 dup + . tst3 9 4 - . ; tst4
[RF replaces colon with <color of the defined word>]

I'm trying to debug <"begin" is unknown>
but the overall structure is confusing.
I don't understand how/what the harness is.
His docos read:-------
Compiler Harness.

 C code compiles by calling a few Forth words.
 These Forth words are defined using a small
       set of built-in words.
 Small table of C entry points allow Forth to
      access system resources.
-----------------------------
Harness Required Words.

 execute-forth
 literal
 compile,
 variable
-----------------------------
Harness Supplied Words.

 macro
 forth
 smudge
 unsmudge
 b,
 windows?
 load
 thru
 heap-dump
 word-dump
-------------------------------
Harness Supplied Entry Points.

 load
 print_number
 key
 emit
 library_load
 library_symbol
------------------
Can someone explain how this harness fits into the:
asm, C, forth, language heirarchy?

== TIA.
