Proof step 18 from proof okbytearray-put-byteval (previous step)

¬ r ≠ (r0 -- i ') .ref, okbytearray(r, st), okbytearray(r, st[rkvs][r0 -- i ', byteval(by)]) ⊦ r0 -- _length ∈ rkvs, r0 -- i ' ∈ rkvs, okbytearray(r, st[rkvs])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 17:
okbytearray(r0, st), okbytearray(r0, st[rkvs][r0 -- i ', byteval(by)]) ⊦ r0 -- _length ∈ rkvs, r0 -- i ' ∈ rkvs, okbytearray(r0, st[rkvs])
