feat(v4.0.0): the defining and compiling words

Browse Source

The fourth layer of the compiler capsule.  compile.v4: INTERPRET's
loop, STATE [ ] : ; EXIT IMMEDIATE LITERAL COMPILE [COMPILE] ' EXECUTE,
CREATE VARIABLE CONSTANT DOES>, and IF ELSE THEN BEGIN UNTIL AGAIN
WHILE REPEAT DO ?DO LOOP +LOOP on a control-flow stack in memory.
forth.v4: the first words of the vocabulary, the in-line ones.

FORTH source now goes in and running code comes out.  49 programmes
were run through the v3 binary and through this; every result agrees,
bar COMPILE, which v3 cannot run.  The code laid down for each control
structure is word for word the expansion DECOMPOSITION.md gives.

A line may have six values on the stack while it is interpreted, and
words called from the interpreter may nest eight deep.
