'create database' with ISQL + ONLINE

Hi, we changed from Informix SE to Informix Online 5.0 with all this developing tools like r4gl, isql, etc. My question is: When you create a database from the isql menu, is there any possibility to change the default dbspace? (I know, you can create the db with a sql-statement like "create db in dbsace") But if you use the isql-menu all databases will be created in the rootdb. I found no hints in the manuals, maybe somone knows a solution! The problem is, that we have some novice users, which will prefer the isql-frontend. So our rootspace will be filled very rapidly, I'm afraid. Thanks, Olaf Hendel TU-Berlin, Germany
