Clear[Names["x*"]] or something. But you probably often have the situation where you have a lot of variables with a variety of names. It drove me nuts too. I finally got CleanSlate.m from Mathsource (available also from Wolfram forum on Compuserve). I was afraid that it would take a rocket scientist to learn it, but finally got desperate enough to try it. It has a lot of capabilities for clearing only certain contexts, all contexts but something etc. etc. But I only use a simple subset of it: ClearInOut[] clears the In and Out (thus saving memory). And CleanSlate[] -- clears out everything, leaving you in the same state as you would be just starting a fresh Mathematica session (well not quite, but that's a long story. But it does the job I need done 99.9% of the time). I like it so much that I made reading in this package part of my init.m file, so that it is automatically present in my MMA session. Jim Larson
