If they're all using the same executable, then the code segment is shared, reducing memory impact. If you use Informix 6.0 or greater, you won't have a back-end process per user, making a traditional 4GL approach more feasible. ----------------------------------------------------------------- Jim Burks jburks@promus.com The Promus Companies Memphis, Tennessee, USA
