Proof step 11 from proof okarray-copy (previous step)

st[r1 -- _length] = intval(i), st[r1 -- _type] .type = mkarraytype(ty0), 0 < i, 0 ≤ j, j < i, 0 ≤ i, r1 ∈ st, is_arrayref(r1, i, st), is_integervalue(st[r1 -- _length]), r1 -- _length ∈ st, ty0 ≤ ty, is_typevalue(st[r1 -- _type]), r1 -- _type ∈ st, ∀ j0. ¬ j0 < 0 ∧ ¬ i ≤ j0 → okval(st[r1 -- j0 '], ty) ⊦ r1 = jvmref, r1 = r0, okval(st[r1 -- j '], ty)

Proof step 10:
st[r1 -- _type] .type = mkarraytype(ty0), st[r1 -- _length] = intval(i), 0 ≤ i, 0 < i, r1 -- _type ∈ st, is_typevalue(st[r1 -- _type]), ty0 ≤ ty, r1 -- _length ∈ st, is_arrayref(r1, i, st), r1 ∈ st, j < i, 0 ≤ j, ∀ j0. ¬ j0 < 0 ∧ ¬ i ≤ j0 → okval(st[r1 -- j0 '], ty) ⊦ r1 = r0, r1 = jvmref, okval(st[r1 -- j '], ty)
