Proof step 20 from proof okarray-copy (previous step)

r0 ≠ r ∧ 0 ≤ j ∧ j < 0 + i, st[r0 -- _length] = intval(i), j < i, 0 ≤ i, r0 ∈ st, is_arrayref(r0, i, st), r0 -- _length ∈ st, okreftype(refval(r0), mkarraytype(byte_type), st), 0 ≤ j, 0 < i, ∀ j0. ¬ j0 < 0 ∧ ¬ i ≤ j0 → is_bytevalue(st[r0 -- j0 ']) ⊦ r0 = jvmref, r = jvmref, is_bytevalue(addarray(r, byte_type, i, st)[r0 -- ((j - 0) + 0) '])

And obtained the following new goals

Proof step 18:
⊦ r ≠ r0 → (addarray(r, ty, i, st)[r0 -- sk]) = st[r0 -- sk]
Proof step 19:
st[r0 -- _length] = intval(i), 0 ≤ i, r0 ∈ st, is_arrayref(r0, i, st), r0 -- _length ∈ st, okreftype(refval(r0), mkarraytype(byte_type), st), 0 ≤ j, 0 < i, j < i, ∀ j0. ¬ j0 < 0 ∧ ¬ i ≤ j0 → is_bytevalue(st[r0 -- j0 ']) ⊦ r0 = jvmref, r = jvmref, r0 = r, is_bytevalue(st[r0 -- j '])
