# KOS_OP_VAR_CLEAR
- **Style**: VAR. Arg = constant pool index of name (post-compile).
- **Stack**: No stack effect. Delete name from namespace.
- **Invariants**: Name in constant pool.
- **Compiler form:** Pre-compile arg = name; post-compile arg = pool index.

**Example:** Delete name "tmp". Pool: 0 = "tmp".
