Clean screen

[Danny 46]

I have a problem with a dev-c program. I need to eliminate part of screen that I am showing, and leaving only what I want. Therefore have to be able to select that point to point remove once shown on screen and in that time. I've tried it with system ("CFA") but this only with him that delete me all of the above. If anyone knows some elegant method of doing this, please get in touch with me or comment on this post.
thanks

That kind of control over the terminal requires something like ncurses
