The reason for that is a query result from a database, each array ref, since I can not join these tables, are each from these tables, and I don't know how many records each one will be returning, that is the reason for this sample code.

The tables are too big, they are already a logic file from 3 different tables each. Thats the only way, I have to get the values from the first and after finding the account numbers I can get the rest from the other table, manipulate the results in the array ref and format a report
