Mnemonic Device
- Soar high and land low.
Explanation
This is a mnemonic to help you remember which bitwise operation sets bits and which one clears them. "Soar" rhymes with OR, and "land" rhymes with AND. To set a bit (turn it high, to 1), OR it. To clear a bit (turn it low, to 0), AND it (with a mask that has a 0 in that position).
