- Text after start is refused, as text.c refuses it: before it jumps, the
ROM reads on to the end of the source; blanks, comments and the ends of
blobs may follow, a token is ERR-AFTER (26), "text after start".
- A token too long where a name, a target or a value is wanted is "name
too long", as text.c says: (MISSING) reports "missing" only when no error
came first. `", keeps "missing", which is text.c's word for both.
- text.c's "address out of range" names the address, not the value.
- The system's source files are one list, v4/sys_files.h: boot.c, the
harness and the nucleus test are made from it.
- The ROM's error codes and words are one list, v4/rom_errors.h: boot.c's
messages, host_map.h's ROM_ERR_* and mkmap's ERR-* are made from it.
- node.h says what v4_node_store does with a ROM address (nothing, as for
any address outside RAM, D-14); test_host_rom_range pins it.

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.
