When reading input from the user in Perl, how to let Perl not display "Terminating on signal SIGINT(2)"?

I'm very new to Perl and currently I'm learning it on Windows 7 with ActiveState Perl. This is my program.

chomp(my @lines = <STDIN>);

foreach (sort @lines) {
    print $_;
}

When running the program, I type some lines of strings then press Ctrl + c to tell the program that I've finished typing. However, after I get my result (generated from print $_;), I also got this message: Terminating on signal SIGINT(2). How to disable this message?

Thanks.

You can handle signals like that:

$SIG{INT} = sub { print("Caught SIGINT but continue!\n"); };

for a keyboard interrupt. It's an exemple.

For Windows, to signify End of Line press Ctrl + Z followed by Enter

Pressing Ctrl + C sends the interrupt signal to your program which is the cause of the Terminating on SIGINT message you are seeing.
