From cc46ad28329ae94065e78b036050a4570329d617 Mon Sep 17 00:00:00 2001 From: Charles KWON OhJun Date: Mon, 6 Apr 2026 15:11:17 +0900 Subject: [PATCH] fix: SOFTSEEK, SET DELETED+INDEX, compound key, SET INDEX TO + stress test Fixes from 77/77 thorough test: - SOFTSEEK uses CurRecNo() (was requiring recNo>0) - SEEK reads SET SOFTSEEK at runtime (was compile-time only) - SkipIndexed skips deleted records when SET DELETED ON - GoTopIndexed skips deleted at top position - evalKeyExprInner TrimSpace on fieldName (compound key fix) - SET INDEX TO uses exprToString (was emitExpr treating as variable) - hasXBaseCommands scans nested blocks (BEGIN SEQUENCE, IF, FOR, etc.) 77/77 thorough test PASS. Stress test (82 items) in progress.
