Solving with multiple unknown variables & more

[leprechaun]

ok I hope I understood. Somehow I had the idea that the calculator should memorize that m was already defined. As suggested I did a search on the forums and read the above link. Did I undersand it correctly that something like the following should be done? If there are programming flaws point them out. I used Han's c-style argv building block. That was a great idea.
Maybe I should save and retstore old fomulae in the geometry app?

Code:


#cas
foo(args)
BEGIN
  LOCAL argv, argc;
  argv:=[args];
  argc:=size(argv);
  
  Instruction(1,2):="GA";
  Instruction(1,3):=plotfunc(argv(1),argv(2));
  CHECK(1);

END;
#end
Ideas for improvement? I remeber that there is a command for automatically switching to the plot view and actiate geometry app. I can't remember.

[/code]

I could call foo(Ekin(m,v),v). Maybe HP could make a refined well designed frontend for the purpose???
