Proof step 17 from proof okbytearray (previous step)

¬ j ≤ 0, val ∈ getarray(r, i, j, st), okarray(r, byte_type, st), i + j ≤ st[r -- _length] .intval, r ∈ st, 0 ≤ i, j ≤ 1, ∀ 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)

Proof step 16:
okarray(r, byte_type, st), val ∈ getarray(r, i, 1, st), 0 ≤ i, r ∈ st, i < st[r -- _length] .intval, 0 < st[r -- _length] .intval, ∀ val, i, st, r, j0. i→n(j0) < i→n(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)
