Proof step 26 from proof okarray-onlymod (previous step)

st[r -- _type] = typeval(mkarraytype(ty0)), st[r -- _length] = intval(st[r -- _length] .intval), 0 ≤ st[r -- _length] .intval, r ∈ st, is_arrayref(r, st[r -- _length] .intval, st0), is_arrayref(r, st[r -- _length] .intval, st), r -- _length ∈ st, ty0 ≤ ty, r -- _type ∈ st, ∀ j0. ¬ j0 < 0 ∧ ¬ st[r -- _length] .intval ≤ j0 → okval(st[r -- j0 '], ty), r0 -- _length ∈ st → st[r0 -- _length] = st0[r0 -- _length], r0 -- _type ∈ st → st[r0 -- _type] = st0[r0 -- _type], ∀ r1, sk. r1 ≠ r0 → st[r1 -- sk] = st0[r1 -- sk], ∀ rk. rk ∈ st ↔ rk ∈ st0 ⊦ st0[r -- _type] .type ≤ mkarraytype(ty), r = jvmref, r = r0
