Did you read and understand the responses you got to how to print out side of foreach loop($k1 $a{$k1}) ??

Declare:

 $my index;

at the beginning of your script.

my $index;
my @message;
my $input = 10;
for my ( 0..$input-1 )
{
    $message[$_][0] = "element 0";
    $message[$_][1] = 42;
}
print "The second array has ", scalar( @{ $message[1] } ), " elements\
+n";
print "They are:\n";
for ( 0..$#{ $message[1] } )
 {
   print "\t", $message[$_][1], "\t", 
}
  print "\t", $message[1], "\t", $message[0] ,"\n";

$_ is a special variable that acts as your $index would if you omit it. Google for perl special variable $_ examples for more info.

marto, the responses in his previous post were excellent but VERY technical. Unless you are familiar with perl and programming lingo, they may be difficult to understand.

"marto, the responses in his previous post were excellent but VERY technical. Unless you are familiar with perl and programming lingo, they may be difficult to understand."

They specifically asked how to print without using a for loop. The responses in the previous thread show examples of doing this, and an explanation is provided. Your code (which uses a for loop to print) does not even compile:

Missing $ on loop variable at derp.pl line 6.

Fixing this problem your code produces:

The second array has 2 elements
They are:
        42              42              ARRAY(0x71b668) ARRAY(0x88cda0
+)

Are you sure this is what you intended to show them?
