# Form `VC` — VC — Vector Compare (with Rc → CR6)

## Bit Layout

| Bits | Field | Meaning |
| --- | --- | --- |
| 0–5 | `OPCD` | primary opcode (4) |
| 6–10 | `VRT` | destination vector register |
| 11–15 | `VRA` | source A |
| 16–20 | `VRB` | source B |
| 21 | `Rc` | record-form flag (updates CR6) |
| 22–31 | `XO` | extended opcode (10 bits) |
