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

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.
