Proof step 18 from proof okarray-putar (previous step)

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

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