Integrity constraint and INPUT ARRAY

Hi, I've got a table with following schema create table tbl ( f1 smallint no null, f2 smallint no null, f3 smallint no null) The problem is when i modify it with INPUT ARRAY and accidently insert new line i can't leave the one, 'cause 4GL says "This field requires an entered value". The same occurs when there are no rows retrivied from the table, I've done nothing and try to exit the INPUT ARRAY. In last case I at least can press interrupt key to escape as far as there is nothing to save. I would not like to change schema because of integrity constraint. Is there workaround how i can leave empty input array line for my case? Thanks in advance, --------------------------------------------------------------- Vadim G.
