Proof step 15 from proof okbytearray (previous step)

okarray(r, byte_type, st), val ∈ st[r -- i '] ', 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)

And obtained the following new goals

Proof step 14:
okarray(r, byte_type, st), 0 < st[r -- _length] .intval, i < st[r -- _length] .intval, r ∈ st, 0 ≤ i, ∀ 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(st[r -- i '])
