Proof step 6 from proof in-1dim-10 (previous step)

0 < i ∨ r ∈ st ⊦ r ∈ addarray(r, val, i, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ r ∈ st → r ∈ addarray(r0, val, i, st)
Proof step 5:
¬ r ∈ st, 0 < i ∨ r ∈ st ⊦ r ∈ addarray(r, val, i, st)

Rule argument

[crewrite-arg: in-1dim-09 , F , [st, i, val, r0, r] → [st, i, val, r, r] ]
