What you have to do is as follow: 1. Put the INPUT ARRAY statement in an infinite while loop. 2. In the BEFORE DELETE clause, ask the question "DO you really want to delete?" If the answer is yes, then EXIT INPUT. This is not the most elegant code. INFORMIX should allow return codes from the BEFORE INSERT and BEFORE DELETE to either go or not go ahead with the DELETE or INSERT. By doing the EXIT INPUT, the cursor will be positioned on the first line (bummer). But so far that's all I come up with. Any one else have a better answer.
