Proof step 13 from proof isarray-addarray (previous step)

∀ j. ¬ j < 0 ∧ ¬ n→i(# vals) ≤ j → oktype(vals[i→n(j)], ty, st) ⊦ is_arrayref(r, n→i(# vals), addarray(r, ty, vals, st)), r = jvmref

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 9:
⊦ i < n→i(# vals) → is_arrayref(r, i, addarray(r, ty, vals, st))
Proof step 12:
¬ n→i(# vals) < n→i(# vals), ∀ j. ¬ j < 0 ∧ ¬ n→i(# vals) ≤ j → oktype(vals[i→n(j)], ty, st) ⊦ is_arrayref(r, n→i(# vals), addarray(r, ty, vals, st)), r = jvmref

Rule argument

[crewrite-arg: isarray-init-01 , F , [st, vals, ty, i, r] → [st, vals, ty, n→i(# vals), r] ]
