Pure beginners question.
I'm creating a hash of arrays like this :
$ihash{$3}{$1} = [...@itab];
For now I was able to get the data using Dumper but I need to create a
"pretty" report.
How do I loop over this hash/hash of arrays to print it out?
Thank you.

Thanks, I'm getting some help from a tutor and you all

Hi Stuart.

I have a hash called fouls. Within that hash, there
are other hashes called offensive, personal, and
shooting. The keys to those hashes are names, like
Smith, Rodriguez, and Chan. and the values to those
names are numbers.
I think if I wanted to access the number of offensive

In your adding lines you add entries line [ $entry ], which means, make
an array reference (the brackets) which has $entry as the first element
of the array. You then have a hash of hashes of arrays (for at least
some entries). If you meant the arrays, you'll have to add a third
loop to the

From a previous post I needed to identify
a particular data structure. It is a hash of hashes.
Now, I need to print the hash out.
I'm using the code from the "Programing
Perl" 3rd edition from O'Reilly on how
to print out the hash and of course I'm
having a problem.

All other comments included, the one thing that hasn't been pointed
out is that this is dangerous.

The code is below; what's pertinent is really the last line.
When I drop the ."\n" the hash prints as expected, but with no line breaks
between records. Assuming concactenating the \n would do it, I threw it into
the print command.
Now it returns a value of 2/8 instead of the hash values. . . what
27 matches
