Proof step 9 from proof okarray-put-08 (previous step)

st[r0 -- _length] = intval(i), st[r0 -- _type] = typeval(mkarraytype(ty0)), r0 -- _type ∈ st[r -- fs ', val0], ty0 ≤ ty, r0 -- _length ∈ st[r -- fs ', val0], is_arrayref(r0, i, st), j < i, r0 -- _length ∈ st, r0 -- _type ∈ st, 0 ≤ i, 0 ≤ j, 0 < i, r0 ∈ st[r -- fs ', val0], r0 ∈ st, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → okval(st[r0 -- j '], ty) ⊦ fs ' = _length, fs ' = _type, r0 = jvmref, okval(st[r0 -- j '], ty)
