Proof step 18 from proof okbar-putbar (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 ']) ⊦ 0 ≤ j ∧ j < i0 → is_bytevalue(st[r -- j ']), r = jvmref, r = r1

Proof step 17:
st[r -- _type] = typeval(mkarraytype(byte_type)), st[r -- _length] = intval(i0), j < i0, 0 ≤ i0, r ∈ st, r -- _type ∈ st, is_arrayref(r, i0, st), r -- _length ∈ st, 0 ≤ j, 0 < i0, ∀ j0. ¬ j0 < 0 ∧ ¬ i0 ≤ j0 → is_bytevalue(st[r -- j0 ']) ⊦ r = jvmref, r = r1, is_bytevalue(st[r -- j '])
