# KOS_OP_VAR2
- **Style**: EXTRA (VAR, VAR, NOARG, NOARG). Row = two constant pool name
  indices (post-compile).
- **Stack**: `[...] → [..., a, b]`. Load both names from the frame namespace
  and push in row order. Both names resolve before either push, so a missing
  name errors with nothing pushed.
- **Invariants**: Names in constant pool.
- **Compiler form:** Never emitted by specials. Produced only by
  `ByteCodeProcessor.pack_runs` (the trailing pack phase), which combines a
  run of two consecutive bare VAR loads (quads first, then one triple or one
  pair). `convert_fast` lowers to FAST2 when
  both names have fast slots (all-or-nothing; a mixed-eligibility row stays
  VAR2).

**Example:** Load "x" then "y". Pool: 0 = "x", 1 = "y".
