Proof step 25 from proof okarray-addarray (previous step)

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

User applied rule case distinction

And obtained the following new goals

Proof step 16:
∀ val. val ∈ vals → okval(val, ty) ⊦ is_arrayref(r, n→i(# vals), addarray(r, ty, vals, st)), r = jvmref
Proof step 24:
∀ val. val ∈ vals → okval(val, ty) ⊦ 0 ≤ j ∧ j < n→i(# vals) → okval(vals[i→n(j)], ty), r = jvmref
