| 19:26 | In the TCL bindings, make sure Tcl_AppendResult() is always terminated by "(char*)0" and not just "0". check-in: ea4d23d1 user: drh tags: trunk | |
| 13:20 | Add the OP_Undef and OP_IsUndef opcodes. With these, use the first register in the result register range as the flag to indicate EOF on an INSERT from a SELECT, rather than allocating a separate boolean register for that task. check-in: 6fb74485 user: drh tags: coroutine-refactor | |

4488 4488 ** Register P2 holds an SQL index key made using the 4489 4489 ** MakeRecord instructions. This opcode writes that key 4490 4490 ** into the index P1.
