use Term::Cap. use the POSIX module to probe certain features of the terminal.
#!/usr/local/bin/perl
use POSIX;
use Term::Cap;
# General terminal line I/O
my $termios = new POSIX::Termios;
$termios->getattr;
# Extract the entry of the terminal type
my $term = Term::Cap->Tgetent( { OSPEED => $termios->getospeed } );
# clear
$term->Tputs('cl', 1, STDOUT);

Shell out and ask the OS to do it:
system $^O eq 'MSWin32' ? 'cls' : 'clear';

$CONSOLE->Cls();
$CONSOLE->Cls( $FG_WHITE | $BG_GREEN );
Where $CONSOLE is your blessed Console object. | [reply]

Come on! I'm surprised no one proposed this classic one:
print " " x 80*25;
You might want to modify the values to fit your screen

print "\n" x 25;
But I guess that's not as cool as printing spaces...
Update: Woohoo! My first post with a negative rep!

Another, less complex method would entail:
print `clear` , "\n";
| [reply] |
|

Why the print stuff?
This is enough:
system('clear');
But it only works on *nix systems, it fails on win32. | [reply]

I'm running activestate perl 5.6.1 for mswin32
and I have found that system ("clear"); doesn't
work but the following code works fine.
#!/usr/bin/perl-w
use strict;
use Win32;
system ("cls");

I:\tmp>clear
'clear' is not recognized as an internal or external command,
operable program or batch file.
so system("clear") won't work because it's not a windows command. "cls" is.

You could invoke the (system-specific) external command:
system "cls"; # dos
system "clear"; # unix
