In some of the sample code that comes with 5.5, and on the OOPs Manual Update
that also comes with it, there is a definition for a new type stream.

Objects are saved on streams. (it was introduced as a way out of the problem
that you can't say "FILE of <object_identifier>")

Well worth a look, all the code is given, and may give a few ideas.
