Proof step 9 from proof getbytearray-putbar-length (previous step)

⊦ # getarray(r, 0, st[r -- _length] .intval, putByteArray(bytes, r0, i, st)) = # getarray(r, 0, st[r -- _length] .intval, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 6:
⊦ 0 ≤ j → # getarray(r, i, j, st) = i→n(j)
Proof step 7:
⊦ j < 0 → # getarray(r, i, j, st) = 0
Proof step 8:
⊦ 0 ≤ j → # getarray(r, i, j, st) = i→n(j)

Rule argument

[crewrite-arg: get-length-01 , F , [st, j, i, r] → [putByteArray(bytes, r0, i, st), st[r -- _length] .intval, 0, r] ]
