Overlapping output?

[Bleric]

Alright, I did a search on the topic, and nothing came up. If there's already been discussion on this, any links would be greatly appreciated.

Anyway. Is there an alternative to using a bunch of delayed printf() statements to debug the robot? Some sort of overlapping output would be awesome =P Ideally, I was hoping there was some third party program which displays the values of different variables. Maybe a GUI of some sort for the robot?

If no such program exists, would it be possible to do something along the lines of

while(1)
{
x = someFunction();
clrscr();
cout << x;
}

(Well, that's what I use in my high school comp sci class, anyway )

Any input / advice would be greatly appreciated
