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

⊦ r1 -- i ' ∈ arraycopy(r, i1, r0, i0, j, st) ↔ r1 -- i ' ∈ st, r1 = r0

User applied rule induction

And obtained the following new goals

Proof step 6:
true, ∀ j0, r1, i, r, i1, r0, i0, st. i→n(j0) < i→n(j) → (true → (r1 -- i ' ∈ arraycopy(r, i1, r0, i0, j0, st) ↔ r1 -- i ' ∈ st) ∨ r1 = r0) ⊦ (r1 -- i ' ∈ arraycopy(r, i1, r0, i0, j, st) ↔ r1 -- i ' ∈ st) ∨ r1 = r0

Rule argument

[INDHYPARG : [STANDARDINDUCTIONTYPE : ], true, false, i→n(j), [] → [], <]
