Proof step 7 from proof copy-in-between (previous step)

0 < j, i0 ≤ j0, j0 < i0 + j, ∀ j1, j0, i0, r0, r, i, st. i→n(j1) < i→n(j) → (j0 < i0 + j1 ∧ i0 ≤ j0 ∧ 0 < j1 → r0 -- j0 ' ∈ arraycopy(r, i, r0, i0, j1, st)) ⊦ r0 -- j0 ' ∈ arraycopy(r, i, r0, i0, j, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ 0 < j → arraycopy(r1, i1, r2, i2, j, st) = arraycopy(r1, i1, r2, i2, j - 1, st[r2 -- (i2 + j - 1) ', st[r1 -- (i1 + j - 1) ']])
Proof step 6:
0 < j, 0 < j, i0 ≤ j0, j0 < i0 + j, ∀ j1, j0, i0, r0, r, i, st. i→n(j1) < i→n(j) → (j0 < i0 + j1 ∧ i0 ≤ j0 ∧ 0 < j1 → r0 -- j0 ' ∈ arraycopy(r, i, r0, i0, j1, st)) ⊦ r0 -- j0 ' ∈ arraycopy(r, i, r0, i0, j - 1, st[r0 -- (i0 + j - 1) ', st[r -- (i + j - 1) ']])
