Proof step 8 from proof okbar-put-byte-01 (previous step)

okbytearray(r, st), okbytearray(r1, st) ⊦ okbytearray(r, st[r1 -- i ', byteval(by)])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ r ≠ rk .ref → (okbytearray(r, st[rk, val]) ↔ okbytearray(r, st))
Proof step 7:
¬ r ≠ (r1 -- i ') .ref, okbytearray(r, st), okbytearray(r1, st) ⊦ okbytearray(r, st[r1 -- i ', byteval(by)])

Rule argument

[crewrite-arg: okbar-put , F , [val, rk, st, r] → [byteval(by), r1 -- i ', st, r] ]
