Proof step 33 from proof okarray-init-04 (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 24:
⊦ n < # vals → (vals + val ')[n] = vals[n]
Proof step 30:
¬ i→n(j) < # vals, 0 ≤ j, j ≤ n→i(# vals), ∀ j0. ¬ j0 < 0 ∧ ¬ n→i(# vals) ≤ j0 → is_bytevalue(vals[i→n(j0)]) ⊦ r = jvmref, is_bytevalue((vals + byteval(by) ')[i→n(j)])
Proof step 32:
i→n(j) < # vals, 0 ≤ j, j ≤ n→i(# vals), ∀ j0. ¬ j0 < 0 ∧ ¬ n→i(# vals) ≤ j0 → is_bytevalue(vals[i→n(j0)]) ⊦ r = jvmref, is_bytevalue(vals[i→n(j)])
