Bug 1: FIELD->NAME in INDEX ON expression
- evalKeyExprInner: strip FIELD->/alias-> prefix before field lookup
- exprToString: handle AliasExpr (FIELD->NAME → "FIELD->NAME")
Bug 2: AsNumInt() on Double returned IEEE 754 raw bits
- Value.AsNumInt(): check tDouble and convert via Float64frombits
- Fixed array index crash when index is result of % modulo
Bug 3: PACK/ZAP crash with open indexes
- OrderListRebuild: fully implemented (was TODO stub)
Saves index info, closes all, sets idxState=nil, recreates
- OrderCreate: set current=-1 during key evaluation (natural GoTo)
- PACK/ZAP: save/restore idxState, rebuild after operation
- Register __DBPACK, __DBZAP, DBRECALL symbol aliases
Harbour vs Five: 45/47 match (96%), 2 diffs are duplicate-key sort order
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
47 test items comparing Harbour and Five output:
- T01-T28: 100% match (CRUD, navigation, SET DELETED)
- T29-T39: 100% match (SEEK exact/partial/softseek)
- T40-T41: Found matches, RecNo differs (duplicate key sort stability)
- T42-T43: 100% match
- T44-T47: Five crashes (PACK with open index)
Known issues found:
- FIELD->NAME syntax not supported in INDEX ON expression
- Modulo % returns Double causing array index hang (Int() workaround)
- PACK crashes when NTX index is open
