Proof step 18 from proof exactarray-put (previous step)

st[r -- _length] = intval(i0), st[r -- _type] .type = mkarraytype(byte_type), r -- _length ∈ st, is_integervalue(st[r -- _length]), is_arrayref(r, i0, st), r -- _type ∈ st, is_typevalue(st[r -- _type]), 0 ≤ i0, r ∈ st ⊦ r = jvmref, exactreftype(refval(r), mkarraytype(byte_type), st[r0 -- i ', byteval(by)]) ∧ is_arrayref(r, i0, st[r0 -- i ', byteval(by)])

Proof step 17:
st[r -- _type] .type = mkarraytype(byte_type), st[r -- _length] = intval(i0), 0 ≤ i0, r ∈ st, is_typevalue(st[r -- _type]), r -- _type ∈ st, is_arrayref(r, i0, st), r -- _length ∈ st ⊦ r = jvmref, exactreftype(refval(r), mkarraytype(byte_type), st[r0 -- i ', byteval(by)]) ∧ is_arrayref(r, i0, st[r0 -- i ', byteval(by)])
