conio.h is in my oppinion a great header, but there is another way to
clear the screen that can be adapted into a portable version. Try
this.

#include <stdio.h>
#include <process.h> /* Not sure if I spelled that right, oops */

void cls(void)
{
    system( "cls" );
    return;
}

What that basically does is ask the operating sytem to clear the
screen. As opposed to conio.h accessing the graphics card dirictly, to
make it portable, unix uses clear instead of cls. So something like
this MIGHT!!! work.

#ifdef (WIN32)
#define cls(void) system( "cls" )
#endif

#ifdef (UNIX)
#define cls(void) system( "clear" )
#endif

Someone who knows more about compiler commands might be able to
correct me if I'm wrong there since I just made it up, but it should
work *8).
