Proof step 6 from proof getbar-putbar-same (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ getbytearray(r, st) = getbytearray(r, 0, st[r -- _length] .intval, st)
Proof step 5:
n→i(# bytes) = st[r -- _length] .intval ⊦ getbytearray(r, 0, (putByteArray(bytes, r, st)[r -- _length]) .intval, putByteArray(bytes, r, st)) = bytes

Rule argument

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