Proof step 14 from proof okbytearray-validref (previous step)

st[r -- _type] = typeval(mkarraytype(byte_type)), st[r -- _length] = intval(i), r -- _length ∈ st, is_arrayref(r, i, st), junkref(str, r, st), r ∈ st, 0 ≤ i, r -- _type ∈ st, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → is_bytevalue(st[r -- j ']) ⊦ r = jvmref, okreftype(refval(r), mkarraytype(byte_type), st) ∧ r ≠ jvmref ∧ r -- _length ∈ st ∧ is_integervalue(st[r -- _length]) ∧ 0 ≤ st[r -- _length] .intval ∧ is_arrayref(r, st[r -- _length] .intval, st) ∧ (∀ j. 0 ≤ j ∧ j < st[r -- _length] .intval → oktype(st[r -- j '], byte_type, st))

Proof step 13:
st[r -- _length] = intval(i), st[r -- _type] = typeval(mkarraytype(byte_type)), r -- _type ∈ st, 0 ≤ i, r ∈ st, junkref(str, r, st), is_arrayref(r, i, st), r -- _length ∈ st, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → is_bytevalue(st[r -- j ']) ⊦ r = jvmref, okreftype(refval(r), mkarraytype(byte_type), st) ∧ (0 ≤ j ∧ j < i → is_bytevalue(st[r -- j ']))
