    Himar, am I missing something here? Isn't this just a case of the Set Relation command?

    GENDBC prog, run on a databse with relationships already set up, produces a program from which you can look at the code necessary to progtrammatically set up relns. etc.

    Or, again, am I missing something in the question?
