A lab is intended to be run in a normal session, and it is expected that the user will experiment while running the lab, or after it is completed. Running them in a special locale, or erasing all definitions after the last lab section is run, would make them less useful. In theory, labs should not redefine standard utilities, and each lab should ensure that required definitions are available. But there is no easy way to enforce that after running a lab, the system is in a clean enough state to run any other lab. The only reliable way to handle this is to restart J when running a new lab. If you know of specific problems when running one lab after another, let me know and I will try to get them fixed. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
