Proof step 17:
st[r -- _type] .type = mkarraytype(ty0), r ∈ st, 0 ≤ st[r -- _length] .intval, ty0 ≤ ty, is_typevalue(st[r -- _type]), r -- _type ∈ st, is_arrayref(r, st[r -- _length] .intval, st), is_integervalue(st[r -- _length]), r -- _length ∈ st, ∀ j. ¬ j < 0 ∧ ¬ st[r -- _length] .intval ≤ j → okval(st[r -- j '], ty) ⊦ r = jvmref, fs ' = _type, fs ' = _length, okarray(r, ty, st[r -- fs ', val])
