Proof step 45 from proof validrefs-primarray (previous step)

st[r -- _type] .type = mkarraytype(ty0), st[r -- _length] = intval(i), 0 ≤ i, r ∈ st, is_primtype(ty), is_arrayref(r, i, st), r -- _length ∈ st, r -- _type ∈ st, is_typevalue(st[r -- _type]), is_arraytype(st[r -- _type] .type), ty0 ≤ ty, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → okval(st[r -- j '], ty) ⊦ r = jvmref, is_array(str, r, st)

Proof step 44:
st[r -- _length] = intval(i), st[r -- _type] .type = mkarraytype(ty0), ty0 ≤ ty, is_typevalue(st[r -- _type]), r -- _type ∈ st, r -- _length ∈ st, is_arrayref(r, i, st), is_primtype(ty), r ∈ st, 0 ≤ i, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → okval(st[r -- j '], ty) ⊦ r = jvmref, is_array(str, r, st)
