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