I'm using open3 method to run a dos command 'DIR', it stops here:
open3($rdr, \*POut, \*PErr, $cmd);
Any one knows what's the problem? Thanks very much! 
#!/usr/bin/perl -w
use strict;
use File::Find;
use File::Copy;
use Time::Local; 

use IPC::Open3;

my $log="TestOpen3.log";
open FHO, ">$log";

select FHO;
&executeCmd("dir * \/b\/s");
close FHO;

exit;
sub executeCmd{
    my ($cmd) = @_;
    print "Execute Command: $cmd\n";
    use Symbol 'gensym'; 
    my $rdr = gensym;
    my $pid = open3($rdr, \*POut, \*PErr, $cmd);
    waitpid( $pid, 0 );
    if((my $returnCode = $? >> 8) !=0){
        print "[ERROR] ($returnCode) : ";
        while(<PErr>) 
        {
            print;
        }
        close PErr;
        die $returnCode;
    }
    while(<POut>) 
    {
        print "\t".$_;
    }
    close POut;
}
