## SET

The description of the `SET` commands apply to the case of a comparison instruction. That is, the condition codes are set according to computation `t = a - b`, where `t`, `a`, and `b` may be interpreted as signed or unsigned depending on the `SET` instruction invoked.

| Instruction | Synonym  | Evaluation                   | Description                    |
| ----------- | -------- | ---------------------------- | ------------------------------ |
| `sete`      | `setz`   | `ZF`                         | Equal / zero                   |
| `setne`     | `setnz`  | `~ZF`                        | Not equal / not zero           |
| `sets`      |          | `SF`                         | Negative                       |
| `setns`     |          | `~SF`                        | Nonnegative                    |
| `setl`      | `setnge` | `SF ^ OF`                    | Less (signed `<`)              |
| `setle`     | `setng`  | <code>(SF ^ OF) \| ZF</code> | Less or equal (signed `<=`)    |
| `setg`      | `setnle` | `~(SF ^ OF) & ~ZF`           | Greater (signed `>`)           |
| `setge`     | `setnl`  | `~(SF ^ OF)`                 | Greater or equal (signed `<=`) |
| `setb`      | `setnae` | `CF`                         | Below (unsigned `<`)           |
| `setbe`     | `setna`  | <code>CF \| ZF</code>        | Below or equal (unsigned `<=`) |
| `seta`      | `setnbe` | `~CF & ~ZF`                  | Above (unsigned `>`)           |
| `setae`     | `setnb`  | `~CF`                        | Above or equal (unsigned `>=`) |

Note how the other condition code evaluations are easy to derive from `setl` and `setb`.
