Proof step 15 from proof okbytearray-put-byteval (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 6:
⊦ okbytearray(r, st) ↔ okarray(r, byte_type, st)
Proof step 14:
okarray(r0, byte_type, 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

Rule argument

[crewrite-arg: okbytearray-01, F, [st, r] → [st, r0]]
