Sorry David, that's even worse.  That way, you don't even have a
chance to get the reference to free it later.  RPG doesn't do
any garbage collection at all (except for objects it implicitly
creates, like Java arrays for array parameters).  Java can't,
because it doesn't know the difference between the 2-statement
version and the nested version.  From its point of view there
are just 2 calls.
