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

r -- j ' ∈ st ∧ st ⊆ st0, st[r -- _type] = typeval(mkarraytype(ty0)), j < st[r -- _length] .intval, r -- _type ∈ st0, st ⊆ st0, r -- _type ∈ st, ty0 ≤ ty, r -- _length ∈ st, is_arrayref(r, st[r -- _length] .intval, st), r -- _length ∈ st0, r ∈ st, 0 ≤ st[r -- _length] .intval, r ∈ st0, 0 ≤ j, 0 < st[r -- _length] .intval, ∀ j0. ¬ j0 < 0 ∧ ¬ st[r -- _length] .intval ≤ j0 → okval(st[r -- j0 '], ty) ⊦ r = jvmref, okval(st[r -- j '], ty)

Proof step 17:
st[r -- _type] = typeval(mkarraytype(ty0)), 0 < st[r -- _length] .intval, 0 ≤ j, r ∈ st0, 0 ≤ st[r -- _length] .intval, r ∈ st, r -- _length ∈ st0, is_arrayref(r, st[r -- _length] .intval, st), r -- _length ∈ st, ty0 ≤ ty, r -- _type ∈ st, st ⊆ st0, r -- _type ∈ st0, j < st[r -- _length] .intval, r -- j ' ∈ st, ∀ j0. ¬ j0 < 0 ∧ ¬ st[r -- _length] .intval ≤ j0 → okval(st[r -- j0 '], ty) ⊦ r = jvmref, okval(st[r -- j '], ty)
