## Control Flow Instructions

### CIMV: Check input maturity verify

| | |
|-------------|-------------------------------------------------------------|
| Description | Set `$rA` to `true` if the `$rC <= tx.input[$rB].maturity`. |
| Operation | ```$rA = checkinputmaturityverify($rB, $rC);``` |
| Syntax | `cimv $rA $rB $rC` |
| Encoding | `0x00 rA rB rC -` |
| Notes | |

Panic if:

- `$rA` is a [reserved register](./main.md#semantics)
- `$rC > tx.input[$rB].maturity`
- the input `$rB` is not of type [`InputType.Coin`](../protocol/tx_format.md)
- `$rB > tx.inputsCount`

Otherwise, advance the program counter `$pc` by `4`.

See also: [BIP-112](https://github.com/bitcoin/bips/blob/master/bip-0112.mediawiki) and [CLTV](#cltv-check-lock-time-verify).

### CTMV: Check transaction maturity verify

| | |
|-------------|--------------------------------------------------|
| Description | Set `$rA` to `true` if `$rB <= tx.maturity`. |
| Operation | ```$rA = checktransactionmaturityverify($rB);``` |
| Syntax | `ctmv $rA $rB` |
| Encoding | `0x00 rA rB - -` |
| Notes | |

Panic if:

- `$rA` is a [reserved register](./main.md#semantics)
- `$rB > tx.maturity`

Otherwise, advance the program counter `$pc` by `4`.

See also: [BIP-65](https://github.com/bitcoin/bips/blob/master/bip-0065.mediawiki) and [Bitcoin's Time Locks](https://prestwi.ch/bitcoin-time-locks).
