Proof step 38 from proof okbytearray (previous step)

true, ∀ 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))) ⊦ okarray(r, byte_type, st) ∧ i + j ≤ st[r -- _length] .intval ∧ 0 ≤ i ∧ ¬ is_bytevalue(val) → ¬ val ∈ getarray(r, i, j, st)

And obtained the following new goals

Proof step 1:
⊦ okarray(r, ty, st) → r ≠ jvmref ∧ r ∈ st
Proof step 37:
val ∈ getarray(r, i, j, st), okarray(r, byte_type, st), i + j ≤ st[r -- _length] .intval, r ∈ st, 0 ≤ i, ∀ 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)
