1. Try making a system call, e.g.,
   
   

   use system();
   system ('cls'); # or equivalent on your system.

2. Or look into the Term::Cap module available on CPAN.
   

   use Term::Cap;
   
   $t = Tgetent Term::Cap {TERM=>undef, OSPEED=>9600};
   
   print $t->Tputs("cl");

3. Or you could look at an even simpler module found again on CPAN, called Term::Screen, which allows you to do something like:
   

   use Term::Screen;
   
   my $terminal = new Term::Screen;
   
   $terminal->clrscr();
   [download]

on unix you can also use this :

# store the terminal escape sequence that clear the screen
$clear = `clear`;

# then, all you need is to print $clear
# anytime you want to clear the screen
print $clear;


# Bonus :
# if you wants to know what the "clear" sequence
# looks like (in decimal)
foreach ( split(//,$clear) ) {
  print ord($_),"\n";
}

Why are using the non-standard module 'system'? If you want to use the system function, just do so. This is Perl, not Python. ;-)

Or, YAWTDI: if you're looking to do full-screen character-based interfaces, you can try Curses.
