5 and 3 are the same cuz non-negative int = positive int. —-Gggfr (talk) 04:52, 27 August 2024 (UTC)
- 3 removes the possibility of
SKIP 0, COPY 0, and PREV 0. That's also why 4 exists, so that only PREV 0 is remvoed, since both SKIP 0 and COPY 0 are equivalent to NOOP. --PkmnQ (talk) 05:11, 27 August 2024 (UTC)
