Proof step 35 from proof okbytearray (previous step)

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, j - 1, st) ∧ val ≠ st[r -- (i + j - 1) ']

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 34:
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) ']
