Proof step 16 from proof okbytearray-put-byteval (previous step)

¬ ( i < 0 ∨ ¬ i < (st[rkvs][r0 -- _length]) .intval ∨ 0 ≤ i ∧ i < (st[rkvs][r0 -- _length]) .intval ∧ r0 -- i ' ∈ st[rkvs] ∧ is_bytevalue(st[rkvs][r0 -- i '])), okbytearray(r0, st), okbytearray(r0, st[rkvs][r0 -- i ', byteval(by)]) ⊦ r0 -- _length ∈ rkvs, r0 -- i ' ∈ rkvs, okbytearray(r0, st[rkvs])

And obtained the following new goals

Proof step 5:
⊦ okbytearray(r, st) ∧ 0 ≤ i ∧ i < st[r -- _length] .intval → (¬ is_bytevalue(st[r -- i ']) ↔ false)
Proof step 15:
okbytearray(r0, st), okbytearray(r0, st[rkvs][r0 -- i ', byteval(by)]), i < st[r0 -- _length] .intval, 0 ≤ i, 0 < st[r0 -- _length] .intval ⊦ r0 -- _length ∈ rkvs, r0 -- i ' ∈ rkvs, okbytearray(r0, st[rkvs]), r0 -- i ' ∈ st
