I am trying to write the debug function below that will display both commands and variables if in debug mode and ask before executing a command. However, the exec command doesn't seem to be working as I inteded. What am I doing wrong? 
{
# executing a DOS copy command
&Debug("system(\"copy c:\\oldversion.txt c:\\version.txt \");", 1);
}

sub Debug
{
  my ($display, $executeable) = (@_);

  if ( $debug == 1 )
  {
     print "$display\n";
     if ($executeable == 1)
     {
        print "Do you wish to execute? (y/n):";
        my $answer = <STDIN>;
        chomp($answer);
        if ($answer ne "y" && $answer ne "Y" ) 
        {
           print "\n";
           $executeable = 0;
        }
     }
  }
  if ($executeable == 1)
  {
      eval { $display };
      if ($@) # $@ contains the exception that was thrown 
      { 
         print "Exception $@"; 
      }
    print "$display executed\n";
  }
}
