my $i = 1;
for my $time(sort {$a<=>$b} keys %Signal_ref)
{
        print"Stimestamp_"."$i : $time\n";
        
        $i++;
        for my $msg(sort keys %{$Signal_ref{$time}})
        {
                print"my signal: $msg\n";
                #print"$Signal_ref{$time}\n";
        }
        
        print "\n";
}


Das ist OK, ich ich bekomme was ich möchte (einfach kopieren und laufen lassen; aber der Hash oben ist anders als der den ich von der Simulation habe (siehe unten, single quote und 2 geschweiften Klammern am Anfang und Ende)

    'PSIP1' => '-0.039999999999992',
    'SBC_SC_A1_AR2' => {
      'DATA' => '22 0D 00 00 20 80 F8 7F  ',

      'DLC' => '8'
    }
  },
  '10.055142' => {

      'DATA' => '11 02 00 00 F1 7F A6 7F  ',
      'DLC' => '8'
    }
  },
};


Damit der Stückcode:

my $i = 1;
for my $time(sort {$a<=>$b} keys %$Signal_ref)
{
        print"Stimestamp_"."$i : $time\n";
        
        $i++;
        for my $msg(sort keys %{$Signal_ref{$time}})
        {
                print"my signal: $msg\n";
                #print"$Signal_ref{$time}\n";
        }
        
        print "\n";
}


Und da geht es nicht mehr.

Wo ist der wesentliche Unterschied zwischen beiden Hash. Worauf muss ich bei dereferenzieren achten!?
