Informix questions

Let's say that I'm an informix programmer/DBA looking for a job. What types of questions should I be able to answer in a technical interview? I worked for 5 years writing C programs with embedded SQL (Informix v4.??) Can I even consider myself an informix programmer or DBA since it is such an old version that I worked on? different report generators? I know that the 4gl has a 4gl language of course - anyone know how hard it is to pick up ? (I've written in Unify Vision 4gl and picked that up no problem)o Any suggestions on finding a job for someone with these qualifications? (I know I'll be asked if i know what triggers are - can anyone explain that)? What type of salary do you think I can ask for with 5 years experience on an old version of informix and C that I learned myself? (I'm no expert in C but I've designed and written my own applications for consulting and full time work related jobs) Any Help is appreciated. Thanks. Helen helen@eisinc.com lawson@larry.wizvax.net
