Proof step 39 from proof okbytearray-put-byteval-equiv (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ okbytearray(r, st) ↔ okarray(r, byte_type, st)
Proof step 38:
okarray(r, byte_type, st[r -- i ', byteval(by)]), i < 0 ∨ st[r -- _length] .intval ≤ i ∨ 0 ≤ i ∧ i < st[r -- _length] .intval ∧ r -- i ' ∈ st ∧ is_bytevalue(st[r -- i ']) ⊦ okbytearray(r, st)

Rule argument

[crewrite-arg: okbytearray-01 , F , [st, r] → [st[r -- i ', byteval(by)], r] ]
