8.7: How do I clear the screen?

    (contributed by brian d foy)

    To clear the screen, you just have to print the special sequence that
    tells the terminal to clear the screen. Once you have that sequence,
    output it when you want to clear the screen.

    You can use the "Term::ANSIScreen" module to get the special sequence.
    Import the "cls" function (or the ":screen" tag):

            use Term::ANSIScreen qw(cls);
            my $clear_screen = cls();

            print $clear_screen;

    The "Term::Cap" module can also get the special sequence if you want to
    deal with the low-level details of terminal control. The "Tputs" method
    returns the string for the given capability:

            use Term::Cap;

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

            print $clear_screen;

    On Windows, you can use the "Win32::Console" module. After creating an
    object for the output filehandle you want to affect, call the "Cls"


            $OUT = Win32::Console->new(STD_OUTPUT_HANDLE);
            my $clear_string = $OUT->Cls;

            print $clear_screen;

    If you have a command-line program that does the job, you can call it in
    backticks to capture whatever it outputs so you can use it later:

            $clear_string = `clear`;

            print $clear_string;
