Printing a hash of hashes of arrays

[Ian]

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.
