Proof step 6 from proof mkvalsr-at (previous step)

n ≤ # refs0, ∀ n0. ¬ # refs0 ≤ n0 → (mkjavavalues(refs0)[n0]) = refval(refs0[n0]) ⊦ n = 0, (refval(r) ' + mkjavavalues(refs0))[n] = refval(refs0[n - 1])

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 5:
n = m + 1, n ≤ # refs0, ∀ n0. ¬ # refs0 ≤ n0 → (mkjavavalues(refs0)[n0]) = refval(refs0[n0]) ⊦ n = 0, (refval(r) ' + mkjavavalues(refs0))[n] = refval(refs0[m])
