Proof step 27 from proof okbytearray (previous step)

st[r -- _type] .type = mkarraytype(byte_type), st[r -- _length] = intval(i1), 0 ≤ i1, r ∈ st, is_typevalue(st[r -- _type]), r -- _type ∈ st, i + i0 < i1, 0 ≤ i, 0 < i0, is_arrayref(r, i1, st), r -- _length ∈ st, ∀ j. ¬ j < 0 ∧ ¬ i1 ≤ j → is_bytevalue(st[r -- j ']), ∀ val, i, st, r, j0. i→n(j0) < i→n(i0 + 1) → (true → (okarray(r, byte_type, st) ∧ i + j0 ≤ st[r -- _length] .intval ∧ 0 ≤ i ∧ ¬ is_bytevalue(val) → ¬ val ∈ getarray(r, i, j0, st))) ⊦ r = jvmref, st[r -- (i + i0) '] ∈ getarray(r, i, i0, st), is_bytevalue(st[r -- (i + i0) '])
