Proof step 12 from proof okarray-addarray-other (previous step)

st[r -- _type] = typeval(ty2), st[r -- _length] = intval(i), ty2 = mkarraytype(ty1), ty1 ≤ ty, is_typevalue(st[r -- _type]), r -- _type ∈ st, 0 < i, 0 ≤ j, j < i, 0 ≤ i, r ∈ st, is_arrayref(r, i, st), r -- _length ∈ st, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → oktype(st[r -- j '], ty, st) ⊦ r = jvmref, r = r0, oktype(st[r -- j '], ty, addarray(r0, ty0, vals, st))

Proof step 11:
st[r -- _length] = intval(i), st[r -- _type] = typeval(mkarraytype(ty1)), r -- _length ∈ st, is_arrayref(r, i, st), r ∈ st, 0 ≤ i, j < i, 0 ≤ j, 0 < i, r -- _type ∈ st, ty1 ≤ ty, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → oktype(st[r -- j '], ty, st) ⊦ r = r0, r = jvmref, oktype(st[r -- j '], ty, addarray(r0, ty0, vals, st))
