[Malvern] Direct Screen Access.

[Richard Forster]

This depends entirely on what you are trying to actually do. For example 
if the calculations are not that excessive and you want to interactively 
  modify function parameters and see the changes on the graphs in real 
time then a spreadsheet is pretty good. You can use the spin button or 
scroll bar tools to set the value within a cell and have a nice 
clickable way of altering it. Then replace the c program with 
appropriate function calculations in the sheet and graph the columns of 
data.
But then again, that might not be applicable for what your friend 
actually needs to do.
