Proof step 26 from proof okarray-put-okval (previous step)

r -- j ' ≠ r -- i ', st[r -- _type] = typeval(mkarraytype(ty0)), st[r -- _length] = intval(i0), 0 ≤ i0, r -- _length ∈ st, is_arrayref(r, i0, st), okval(val, ty), r -- _type ∈ st, ty0 ≤ ty, r ∈ st, j < i0, 0 ≤ j, 0 < i0, ∀ j0. ¬ j0 < 0 ∧ ¬ i0 ≤ j0 → okval(st[r -- j0 '], ty) ⊦ j = i, r = jvmref, okval(st[r -- j '], ty)

Proof step 25:
st[r -- _type] = typeval(mkarraytype(ty0)), st[r -- _length] = intval(i0), 0 ≤ i0, r -- _length ∈ st, is_arrayref(r, i0, st), okval(val, ty), r -- _type ∈ st, ty0 ≤ ty, r ∈ st, j < i0, 0 ≤ j, 0 < i0, ∀ j0. ¬ j0 < 0 ∧ ¬ i0 ≤ j0 → okval(st[r -- j0 '], ty) ⊦ j = i, r = jvmref, okval(st[r -- j '], ty)
