Proof step 7 from proof getbar-putbar (previous step)

∀ r, r1, st. r ≠ r1 → getbytearray(r, putByteArray(bytes0, r1, st)) = getbytearray(r, st) ⊦ r = r1, getbytearray(r, putByteArray(by ' + bytes0, r1, st)) = getbytearray(r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ putByteArray(bytes, r, st) = putByteArray(bytes, r, 0, st)
Proof step 6:
⊦ r ≠ r0 → getbytearray(r, putByteArray(bytes, r0, i0, st)) = getbytearray(r, st)

Rule argument

[crewrite-arg: putByteArray-all , F , [st, r, bytes] → [st, r1, by ' + bytes0] ]
