I worked on my problem a little further and have a little more information to share. The declare statement that fails consistently follows a select statement that returns zero rows (and sqlcode 100 and sqlstate '02000'). If I ommit the select statement from the code or set sqlcode to 0 before calling the declare statement, the declare statement works fine. It appears as though the declare statement is not updating the sqlca structure. Is this by design for the ecpg options that I'm using? Did I pick up bad habits while using Informix? Thanks ...
