Proof step 11 from proof exactarray-putbar (previous step)

st[r1 -- _length] = intval(j), st[r1 -- _type] = typeval(mkarraytype(byte_type)), r1 -- _type ∈ st, r1 ∈ st, r1 -- _length ∈ st ⊦ r = r1, r1 = jvmref, (∀ j0. 0 ≤ j0 ∧ j0 < j → r1 -- j0 ' ∈ putByteArray(bytes, r, i, st)) ↔ is_arrayref(r1, j, st)

And obtained the following new goals

Proof step 10:
st[r1 -- _length] = intval(j), st[r1 -- _type] = typeval(mkarraytype(byte_type)), r1 -- _type ∈ st, r1 ∈ st, r1 -- _length ∈ st ⊦ r = r1, r1 = jvmref, (∀ j0. ¬ j0 < 0 ∧ ¬ j ≤ j0 → r1 -- j0 ' ∈ st) ↔ is_arrayref(r1, j, st)
