Re: Will hash of hashes work?

It would help all of us if you:

Show us a relevant part of your input CSV-file;
Let us know what the intended output should look like (based upon the example input file you provide).

Otherwise we can keep on guessing what you have and what you need and none would be the wiser.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
