Proof step 5 from proof getbar-putbar-same (previous step)

n→i(# bytes) = st[r -- _length] .intval ⊦ getbytearray(r, 0, (putByteArray(bytes, r, st)[r -- _length]) .intval, putByteArray(bytes, r, st)) = bytes

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ putByteArray(bytes, r, st) = putByteArray(bytes, r, 0, st)
Proof step 3:
⊦ (putByteArray(bytes, r, i, st)[r0 -- _length]) = st[r0 -- _length]
Proof step 4:
⊦ j = n→i(# bytes) → getbytearray(r, i, j, putByteArray(bytes, r, i, st)) = bytes

Rule argument

[crewrite-arg: putByteArray-all, F, [st, r, bytes] → [st, r, bytes]]
