Hi haukex, Thanks for your response. I want to write a perl scirpt with expectation below: - Input values from keyboard - Output those values in a tables (3 rows, 4 columns ) using Text:Diff:Table This is my code:

Input values from keyboard 

$a = <STDIN>;
my ( @codecs, @channelCap, @percentage );    ## declare codecs variabl
+e

for ( my $i = 0 ; $i < $a ; $i++ ) {
    print( "Codec " . ( $i + 1 ) . " = " );
    $tmp = <STDIN>;
    push @codecs, $tmp;
    print( "Channel capacity of codec " . ( $i + 1 ) . " = " );
    $tmp = <STDIN>;
    push @channelCap, $tmp;
    print( "Percentage of codec " . ( $i + 1 ) . " = " );
    $tmp = <STDIN>;
    push @percentage, $tmp;
}

Assuming i = 3 There're 3 parameters need to input: type of codecs @codecs = (g711, g722, g729); @channelCap = (1000, 2000, 3000) ; @percentage = (0.5, 0.3, 0.2)

Output 4 columns: No. | Codec | ChannelCap | Percentage. Each parameter has corresponding values (here is 3). This is the number of row need to show. 

print "No.   Codec  ChannelCap   Percentage\n";
print diff \@codecs, \@channelCap, \@percentage,
  { STYLE => 'Table' };

Actually, I only get output bellow: 
Please input the number of codec that using 3
Codec 1 = g711
Channel capacity of codec 1 = 1000
Percentage of codec 1 = 0.5
Codec 2 = g722
Channel capacity of codec 2 = 2000
Percentage of codec 2 = 0.3
Codec 3 = g729
Channel capacity of codec 3 = 3000
Percentage of codec 3 = 0.2
No.   Codec  ChannelCap   Percentage
Not a HASH reference at C:/Strawberry/perl/vendor/lib/Text/Diff.pm lin
+e 46, <STDIN> line 10.
