word.f18: (NEXT-TOKEN) reads the console or a macro being expanded; labels,
branches by name (a label of the word, or a word, now or later), the
table of branches waiting, end of word, FOR/NEXT/UNEXT, macros, &NAME,
CONST+N, and (ONE), which dispatches a token. A forward branch to a name
not yet defined waits on a placeholder symbol, filled in by (DEFINE).
dir.f18: constant set here #, ", store, and start, which resolves, clears
the tables the ROM used and runs the word it names. main.f18: the ROM
itself, entry 12; on an error it stops at (ROM-FAILED) with the code and
line in its state, for the loader to report. sym.f18 generalized: any
counted string, placeholders, a hash of only a name's own cells.
test_host_rom_asm.c gives test_text.c's own texts (accepted and refused),
its four real definitions and the ROM's directives to text.c and to the
ROM: the same words, the same errors on the same lines, at both widths.
The ROM is 2036 words.

(FIND) ( -- rec | 0 ), (DEFINE) ( value kind -- ) and (OPCODE) ( -- op | -1 ),
entries 3-5. Names are refused as text.c's define refuses them, compared
case by case with text.c; a set variable may be set again. 256 hash heads,
records growing up and names growing down in dictionary space, used only
while the ROM assembles. text.c gains the data directives #, and ", (the
ROM's language; its mnemonic and reserved-word tables are data); the
nucleus image is byte-identical.
