Proof step 20 from proof okarray-putbar-same-03 (previous step)

st[r -- _type] = typeval(mkarraytype(byte_type)), st[r -- _length] = intval(i0), 0 ≤ i0, r ∈ st, r -- _type ∈ st, is_arrayref(r, i0, st), r -- _length ∈ st, ∀ j0. ¬ j0 < 0 ∧ ¬ i0 ≤ j0 → is_bytevalue(st[r -- j0 ']) ⊦ r = jvmref, is_arrayref(r, i0, putByteArray(bytes, r, i, st)) ∧ (0 ≤ j ∧ j < i0 → is_bytevalue(putByteArray(bytes, r, i, st)[r -- j ']))

And obtained the following new goals

Proof step 12:
st[r -- _type] = typeval(mkarraytype(byte_type)), st[r -- _length] = intval(i0), 0 ≤ i0, r ∈ st, r -- _type ∈ st, is_arrayref(r, i0, st), r -- _length ∈ st, ∀ j0. ¬ j0 < 0 ∧ ¬ i0 ≤ j0 → is_bytevalue(st[r -- j0 ']) ⊦ is_arrayref(r, i0, putByteArray(bytes, r, i, st)), r = jvmref
Proof step 19:
st[r -- _type] = typeval(mkarraytype(byte_type)), st[r -- _length] = intval(i0), 0 ≤ i0, r ∈ st, r -- _type ∈ st, is_arrayref(r, i0, st), r -- _length ∈ st, ∀ j0. ¬ j0 < 0 ∧ ¬ i0 ≤ j0 → is_bytevalue(st[r -- j0 ']) ⊦ 0 ≤ j ∧ j < i0 → is_bytevalue(putByteArray(bytes, r, i, st)[r -- j ']), r = jvmref
