Proof step 34 from proof okbytearray (previous step)

j = i0 + 1, okarray(r, byte_type, st), i + j ≤ st[r -- _length] .intval, r ∈ st, 0 ≤ i, 1 < j, 0 < j, ∀ val, i, st, r, j0. i→n(j0) < i→n(j) → (true → (okarray(r, byte_type, st) ∧ i + j0 ≤ st[r -- _length] .intval ∧ 0 ≤ i ∧ ¬ is_bytevalue(val) → ¬ val ∈ getarray(r, i, j0, st))) ⊦ r = jvmref, is_bytevalue(val), ¬ val ∈ getarray(r, i, i0, st) ∧ val ≠ st[r -- (i + j - 1) ']

Proof step 33:
okarray(r, byte_type, st), i + i0 < st[r -- _length] .intval, r ∈ st, 0 ≤ i, 0 < i0, ∀ val, i, st, r, j0. i→n(j0) < i→n(i0 + 1) → (true → (okarray(r, byte_type, st) ∧ i + j0 ≤ st[r -- _length] .intval ∧ 0 ≤ i ∧ ¬ is_bytevalue(val) → ¬ val ∈ getarray(r, i, j0, st))) ⊦ r = jvmref, is_bytevalue(val), ¬ val ∈ getarray(r, i, i0, st) ∧ val ≠ st[r -- (i + i0) ']
