There is a package called "CleanSlate" which will utterly restore Mathematica to its condition at start-up. But if you don't feel like hunting that down, Clear["Global`*"] should do the trick rather easily. Or define a function such as this at the start of each session: AllClear:= ( confirm = StringTake[InputString["Confirm clear by typing 'y'"],1]=="y"; If[confirm, (ClearAll["Global`*"];Remove["Global`*"]),Null]); Protect[AllClear]; You can omit the prompt if you want, of course, like so: AllClear:=(ClearAll["Global`*"]; Remove["Global`*"]); Protect[AllClear]; / :@-) Scott \ Unsophisticated, but I get by.
