use strict;
use warnings;

my $output = "data";

my $out;
for (;;) {
    print("Do you want to output to (S)creen or to (F)ile? ");
    chomp( $out = uc( <STDIN> ) );
    last if $out eq 'S' or $out eq 'F';
    print("Invalid input. Please type either S or F.\n");
}

if ($out eq 'S') {
    print $output;
}
else  # $out eq 'F'
{
    for (;;) {
        print("Please enter filename: ");
        chomp( my $save = <STDIN> );

        if ( $save !~ /^[a-zA-Z][a-zA-Z_0-9]*\Z/ ) {
            print("Invalid input. Please begin with a letter and do no
+t add extension, it will be added automatically.\n");
            redo;
        }

        $save .= ".ext";

        if ( -e $save ) {
            my $overwrite;
            for (;;) {
                print("Filename exists. Overwrite? (Y) or (N) ");
                chomp( $overwrite = uc( <STDIN> ) );
                last if $out eq 'Y' or $out eq 'N';
                print("Invalid input. Please type either Y or N.\n")
            }


            redo if $overwrite eq 'N';
        }

        open( my $fh_out, '>', $save )
           or die "Unable to create $save: $!\n";

        print $fh_out $output;
