Proof step 13 from proof compatarray-void (previous step)

st[r -- _length] = intval(i0), st[r -- _type] .type = mkarraytype(void_type), 0 ≤ i0, r ∈ st, 0 < i0, 0 ≤ i, is_arrayref(r, i0, st), is_integervalue(st[r -- _length]), r -- _length ∈ st, i < i0, ∀ j. ¬ j < 0 ∧ ¬ i0 ≤ j → compat(str, st[r -- j '], void_type, st) ⊦ r = jvmref, st[r -- i '] = refval(jvmref)

Proof step 12:
st[r -- _type] .type = mkarraytype(void_type), st[r -- _length] = intval(i0), 0 < i0, 0 ≤ i0, i < i0, r -- _length ∈ st, is_arrayref(r, i0, st), 0 ≤ i, r ∈ st, ∀ j. ¬ j < 0 ∧ ¬ i0 ≤ j → compat(str, st[r -- j '], void_type, st) ⊦ st[r -- i '] = refval(jvmref), r = jvmref
