Four audit findings around correctness/consistency in std.ch and the
SORT/UPDATE/TOTAL handlers:
* #13: TOTAL/UPDATE key idiom inconsistency documented as inherent.
TOTAL evaluates `<key>` only in the source workarea so verbatim
`<{key}>` (alias-qualified or `_FIELD->`-prefixed by the user)
works. UPDATE evaluates the same block in BOTH master and detail
context, so it must wrap as `_FIELD-><key>` to dispatch to
whichever WA is selected at eval time. The two rules look alike
but their evaluation contexts differ — also documented in
std.ch alongside both rules so the asymmetry isn't a surprise.
Plus: TOTAL TO and ON are now mandatory (matching the COUNT/
UPDATE pattern from Wave 1) — bare TOTAL would have produced
broken syntax via the unconditional `<(f)>`/`<{key}>` template
references.
* #15/#16: SDF / DELIMITED variants of COPY and TO PRINTER /
TO FILE variants of LIST / DISPLAY are now matched by stub
rules (placed *before* the regular rules so they win) that
expand to a new `__dbNotImpl(reason)` RTL primitive raising a
clear `&hbrt.HbError`. BEGIN SEQUENCE / RECOVER catches the
panic, so callers get a real error instead of the previous
silent dispatch-to-regular-DBF-copy.
* #19: SORT /C (case-insensitive) now actually folds case before
the string compare, instead of being silently treated as
ascending. Suffix parser also rebuilt as a multi-letter scanner
so `name/CD`, `name/DC`, `name/C/D`, `name/D/C` all parse the
same way — combine /C and /D freely. Unknown suffix letters
(e.g., `name/X`) leave the suffix attached to the field name
so a stray slash in user input doesn't get silently mangled
into a broken field reference.
* #27 SET DELETED: verified with a regression test that
`SET DELETED ON` causes COUNT/COPY (and by extension
SORT/TOTAL/JOIN/UPDATE — all of which iterate via Area.Skip)
to skip rows marked deleted. The filtering is implemented at
the workarea level (skipFilter in dbf.go honors hbrdd.IsSetDeleted)
so no RTL changes were needed; this commit just adds the
coverage so the behavior doesn't silently regress.
