It's a very good point you bring up. I'm actually using Text::CSV_XS and using the print method to print the arrayref. The reason why I'm doing this is because other programs have to interact with the CSV files.

I'm keeping two different databases for information about receiving images: one for partial images, one for missing images. (I don't want to get into more one-off detail, but I will say that this is in support of the Phoenix Mars Lander...) Depending on the database you're manipulating, there could be 5 or 8 different fields, and the process is always evolving.

I would write a GUI for this but quite frankly I don't know how. I taught myself Perl a few months ago to get my job done effectively, so what I've been doing is pretty quick and dirty.
