Proof step 41 from proof okarray-put-07 (previous step)

⊦ refval(r) = val, okarray(val, ty, i, st[r -- sk, val0]) ↔ okarray(val, ty, i, st)

User applied rule insert rewrite lemma

Proof step 1:
⊦ okarray(val, ty, i, st) ↔ okreftype(val, mkarraytype(ty), st) ∧ val .refval ≠ jvmref ∧ (val .refval -- _length) × intval(i) ∈ st ∧ 0 ≤ i ∧ is_arrayref(val .refval, i, st) ∧ (∀ j. 0 ≤ j ∧ j < i → oktype(st[val .refval -- j '], ty, st))
Proof step 40:
⊦ refval(r) = val, okreftype(val, mkarraytype(ty), st[r -- sk, val0]) ∧ val .refval ≠ jvmref ∧ (val .refval -- _length) × intval(i) ∈ st[r -- sk, val0] ∧ 0 ≤ i ∧ is_arrayref(val .refval, i, st[r -- sk, val0]) ∧ (∀ j. 0 ≤ j ∧ j < i → oktype(st[r -- sk, val0][val .refval -- j '], ty, st[r -- sk, val0])) ↔ okarray(val, ty, i, st)
