Theorem okarray-byte-01

⊦ st[r -- (i0 + i) '] .byteval = st[r0 -- (j0 + i) '] .byteval ∧ okarray(r, byte_type, st) ∧ okarray(r0, byte_type, st) ∧ i < j ∧ i0 + j < st[r -- _length] .intval ∧ j0 + j < st[r0 -- _length] .intval ∧ 0 ≤ i0 + i ∧ 0 ≤ j0 + i → (st[r -- (i0 + i) '] = st[r0 -- (j0 + i) '] ↔ true)
