No great biggie here.

I'm replacing a system from its FPD26 days, and the tables still need to be used by the old system. There are cases where there's a 1-m reln. so as I create a certain rec I need to create <= 3 related table recs. I'm afraid of crashes during this process, or during my programmed cascaded delete

I was wondering if anyone knew of, or has developed a clever way around the fact that you can't use transactions here, as the old tables aren't part of a dbc. The only way I can think of is to keep track of newly created recs and deleting them if, say, a related TableUpdate() fails, or say, using RECALL when part of a cascaded delete fails.
