Proof step 22 from proof stsub-copy (previous step)

newref(r0, st) ⊦ st ⊆ arraycopy(r, i, r0, i0, j, st0) ↔ st ⊆ st0, r0 = jvmref

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ st1 ⊆ st2 ↔ (∀ rk. rk ∈ st1 → rk ∈ st2 ∧ st1[rk] = st2[rk])
Proof step 21:
newref(r0, st) ⊦ (∀ rk. rk ∈ st → rk ∈ arraycopy(r, i, r0, i0, j, st0) ∧ st[rk] = (arraycopy(r, i, r0, i0, j, st0)[rk])) ↔ st ⊆ st0, r0 = jvmref
