Proof step 24 from proof okbytearray-put-field (previous step)

⊦ fs ' = _length, fs ' = _type, okarray(r, byte_type, st[r0 -- fs ', val]) ↔ okarray(r, byte_type, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ r ≠ r1 → (okarray(r, ty, st[r1 -- sk, val]) ↔ okarray(r, ty, st))
Proof step 23:
¬ r ≠ r0 ⊦ fs ' = _length, fs ' = _type, okarray(r, byte_type, st[r0 -- fs ', val]) ↔ okarray(r, byte_type, st)

Rule argument

[crewrite-arg: okarray-put-other , F , [val, sk, r1, st, ty, r] → [val, fs ', r0, st, byte_type, r] ]
