8.7: How do I clear the screen?

If you only have do so infrequently, use "system":

system("clear");

If you have to do this a lot, save the clear string so you can print it
100 times without calling a program 100 times:

$clear_string = `clear`;
print $clear_string;

If you're planning on doing other screen manipulations, like cursor
positions, etc, you might wish to use Term::Cap module:

use Term::Cap;
$terminal = Term::Cap->Tgetent( {OSPEED => 9600} );
$clear_string = $terminal->Tputs('cl');

Working code is greatly appreciated.

A reference to Term::ANSIScreen would fit well here, as would one to
Win32::Console.
