   Tried it and it come up as “‘clear’ is not recognized as an operable external command, operable program or batch file”
   Replaced “clear” with “cls” (DOS clear screen) and it works fine.

   Indeed, system(‘clear’) works only on Unix-based systems. So for multiplatform programs, that’s _not_ good.

   Printing the Form Feed (ASCII: 12) character should do the trick. I haven’t tried that, though.

   Thanks Marc, system(“cls”) works in Windows.

   Printing the Form Feed character (\f) doesn’t appear to work in Windows. It adds an ‘ankh’ or ‘venus’ symbol to the screen.

   CODE:
   print “This text should not be visible”;
   #print “14″;
   #print “\xC”;
   print “\f”;
   print “This page left blank intentionally.”;

   OUTPUT:
   This text should not be visible♀This page left blank intentionally.

   That first commented print statement didn’t post accurately. It should be a backslash followed by the octal 014.

   Does the content code (One shown for issue) apply/work for a macintosh?
