Stored Procedures and Serial Values

I just finished writing a stored procedure that inserts a record into a table with a serial value column. With 4gl to find out what serial value was assigned to the record just inserted I would access SQLCA.SQLERRD[2]. However, how do I find out what serial value was assigned from within the stored procedure. I looked at SQLCA.SQLEERD[2] after I executed the stored procedure from 4gl but all it returned was zero. By the way I am using Informix 4gl 4.16.UC1 and Informix SE 5.07.UC1 on SCO Unixware 2.03 Thanks Peter pdiazdeleon@infinityhealthcare.com
