I'm throwing together a script to do some file processing. The basic idea is that the script will handle a set of files, processing each file in turn.

As it looks at each file, it should look at the records in the file, and process particular sections of the record based on their character position.

I'm fairly happy with most of the above, but what I'm trying to do is build a data structure so that I can make the script as flexible as possible.

I have a feeling that what I'm looking for is a hash of arrays of arrays - something like:

filename1 => [field_name1, start_position, length ],
             [field_name2, start_position, length ],
                  ..             ..          ..
             [field_namen, start_position, length ]
filename2 => [field_name1, start_position, length ],
             [field_name2, start_position, length ],
                  ..             ..          ..
             [field_namen, start_position, length ]

My problem is that I just can't see how to code that structure up. I'd prefer to use pushes, but I can't come up with a syntax that works. Of course, I might just be going about this all wrong, but I'd welcome any suggestions.

Thanks, Simon
