WORD, the dictionary words and the code generator run underneath
whatever the user has on the stacks, which are ten and nine deep (D-2).
Measured, they used five to seven data cells of their own, leaving a
line about three. Each now keeps what it works on in its file's
scratch cells and has at most three cells on the data stack; , calls
nothing; and the longest chains of calls are shorter.
The public words of core.v4, input.v4 and dict.v4 get dictionary
headers. NUMBER is split so the interpreter can have a flag instead of
NODE-ERROR. The host-node tests share one memory map, host_map.h.

The second layer of the compiler capsule, v4/capsule/dict.v4: HERE ALIGN
ALLOT , C, 2, PAD LATEST; an entry layout reached entirely from the xt,
with >LINK LFA LINK> >NAME NFA NAME> CFA PFA >BODY TRAVERSE SMUDGE
HIDDEN on it; and FIND and ' .
FIND is FORTH-79's and v3's. ' is FORTH-79's: the parameter field
address, which for a code word is what FIND gives. ALLOT counts cells
(D-1). 31 characters of a name are significant.
Executed at both cell widths against a list of 300 entries kept in C.
WORD no longer holds its length on the return stack.

Ruled 2026-10-04: standard words follow the standard where v3 did not.
EXPECT takes up to n characters (v3 took n-1) and does nothing for
n <= 0. QUERY takes up to 80 (v3: 1024). WORD stores the delimiter it
met, or a zero at the end of the text, after the word, and leaves >IN
just past that one delimiter (v3 skipped them all and stored a zero);
the word may be up to 255 characters (v3: 62).

The first layer of the compiler capsule, on the host node: TIB >IN SPAN
SOURCE BL EXPECT QUERY WORD ENCLOSE CONVERT NUMBER and the comment
words. The definitions are text, v4/capsule/core.v4 (the core words
they rest on) and v4/capsule/input.v4, assembled by the text assembler,
which can now read a file.
EXPECT, QUERY, WORD and ENCLOSE behave as v3's. CONVERT and NUMBER are
FORTH-79 (ruled 2026-10-04): any BASE, a double in the standard order,
and NUMBER returns a signed double or sets NODE-ERROR.
Executed at both cell widths against C and against values recorded from
the v3 binary.
