      I do not believe that EVAL() will allow any efficiency for user-entered
      equations. The original idea is far beyond my capabilities. The thought was let
      user enter two most likely distinct linear equations, in any form, let user
      select data for plotting purposes on his own effort, and let the program check
      the user's decisions. A graphical solution would be displayed AS A GRAPH, and
      the result of the user's decision for the solution would also be displayed on
      the same graph for user to compare. I believe this is beyond my capability.
