Proof step 28 from proof okarray-init-04 (previous step)

0 ≤ j, 0 ≤ j, j ≤ n→i(# vals), n→i(# vals) ≤ j, ∀ j0. ¬ j0 < 0 ∧ ¬ n→i(# vals) ≤ j0 → is_bytevalue(vals[i→n(j0)]) ⊦ r = jvmref, is_bytevalue((vals + byteval(by) ')[i→n(j)])

And obtained the following new goals

Proof step 27:
∀ j0. ¬ j0 < 0 ∧ ¬ n→i(# vals) ≤ j0 → is_bytevalue(vals[i→n(j0)]) ⊦ r = jvmref, is_bytevalue((vals + byteval(by) ')[# vals])
