Proof step 31 from proof okarray-08 (previous step)

is_integervalue(val), okarray(r, int_type, st), r ∈ st ⊦ r = jvmref, okarray(r, int_type, st[r0 -- j ', val])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ r ≠ r0 → (okarray(r, int_type, st[r0 -- sk, val]) ↔ okarray(r, int_type, st))
Proof step 30:
¬ r ≠ r0, is_integervalue(val), okarray(r, int_type, st), r ∈ st ⊦ r = jvmref, okarray(r, int_type, st[r0 -- j ', val])

Rule argument

[crewrite-arg: okarray-06 , F , [val, sk, r0, st, r] → [val, j ', r0, st, r] ]
