CSV Comma Separated Values. A popular export/import
option for databases and spreadsheets. Wikipedia is
a good source if you want/need more detail. There
are conversion routines (csv.ijs) distributed with J.
CSV avoids fixed length rows, but as such are a "ragged
array" that isn't "first class" in J. A list of boxes
is similar in spirit to CSV and there are routines in
csv.ijs to switch between the two forms.
The real appeal for fixed records, when there are a
lot of them, is that they can be in a file that is
memory mapped to a rectangular array and then dealt
with in ways comfortable and efficient in J.

I'm a newbie at this. Don't exactly understand what a CSV is, but
perhaps the first time an abbreviation is used, could it be written
out, with the abbreviation in parens. This is the way many
technical reports are written - a nice courtesy.
At any rate, on the subject, in addition to a matrix of fixed length
rows, what's wrong with a list of boxes?
