Seamless migration of 4GL aplication developed on SE to ONLINE?

Hi OnLiners, Is there such thing as a seamless migration of SE application to Online We have quite a number of 4gl applications written on SE and are thinking of migrating from SE to Online (Online 5.01 first). We tested with one application and we got error message -1376 SQL INFORMIX-Online or program variable mismatch warning. We can't see anything wrong with our application. Has anyone encounter this error? For people who have moved their 4gl applications developed on SE to Online, can you please share your experiences. What are some of the things we should look out for? Please advise! - Ken Chow kcchow@solomon.technet.sg fax#: 65-2211322 PS. The platform we are currently using is SCO Unix 3.2.4
