>However, if you're going to switch work areas you shouldn't use this way, because SELECT can get confused and yield wrong result (usually GPF :). So, for multi-table processings you probably should use SCAN. Certainly, I cannot state it by sure without knowing what exactly you want to process.
Aha. So that possible? Well we want to scan a table which contains filenames of all the tables we will be using in an application. So the way you just mentioned IS possible I guess?
Thanks for your reply!
