Q: How to clear variables?
If I run a Mathematica 3.0 notebook, and forget to define a variable I subsequently use, Mathematica will grab the last value for that variable, if it exists, even from another program, during the current session. Is there a line, or lines, of code I can place at the start of a notebook that says to forget all values, both numerica and symbolic, of all variables? Ed McBride, P.E.
