Proof step 24 from proof okarray-put-02 (previous step)

okarray(val, byte_type, i, st) ⊦ okarray(val, byte_type, i, st[r0 -- j ', byteval(by)])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ refval(rk .ref) ≠ val → (okarray(val, ty, i, st[rk, val0]) ↔ okarray(val, ty, i, st))
Proof step 23:
¬ refval((r0 -- j ') .ref) ≠ val, okarray(val, byte_type, i, st) ⊦ okarray(val, byte_type, i, st[r0 -- j ', byteval(by)])

Rule argument

[crewrite-arg: okarray-put-07 , F , [val0, rk, st, i, ty, val] → [byteval(by), r0 -- j ', st, i, byte_type, val] ]
