Try using the module Win32::Console::ANSI, and read its documentation.   It should do what you want.

For example:

use strict;
use warnings;

use Win32::Console::ANSI;

print "If you can read this, CSI is not working.\n";
print "\033[2J" ;   # Clear screen
print "If this is the first line displayed, CSI is OK.\n";

By the way, you need to use '#' as a comment character in Perl ("/* ... */" and "//" are for C and C++).
