Hi to everyone. The following problem was frustrating me for the last few days. The problem lays in this part of my code 
sub returnVersion()
{
   my $cmdToExecute = "dds_cmd -Version ";
   my $versionNum;
   my $PH;
   if (!open($PH, "$cmdToExecute 2>&1 |")) {
      print STDERR "Failed to execute command:($cmdToExecute)--$!\n";
      exit 1;
   }

   while (my $line = <$PH>) {
      if (index($line, "Command Execution ") != -1){
         $line =~ s/^.+version\s|\.0.$//g;
         $versionNum = $line;
      }
   }
   close($PH);
   return $versionNum;
}

So the execution hangs on line "while (my $line = <$PH>) {".

If I execute the "cmdToExecute" manually on cmd works fine-returning 3 lines of text as expected. If I separate this code in separate .pl file and execute it also works fine-and the command returns 3 lines of text.

I don't know why is this happening and why it wont work in my code.

And the strange is that this problem appears only on win2003. On every other platform works fine
