Subject: Re: Appending to a CSV file

I realize that I am jumping late into this thread. I do not understand
why the responses to "How to append to a csv file" are so complex. Why
do you need a csv module to create, edit, and/or add records to a csv
file.

As a newbie, I have written Ruby scripts that created csv file and
appended records to existing csv files without having the need for a
csv module. To append a record, I simply open the file in 'a' mode
(have not needed the a+ mode yet), write the record to the file and
then close file.

I apolized if I am out of term and stuck my nose in the wrong place.
