the contents of a field. All I can think of, however, is a clunky DL
(define line) and series of SE/S /,/ followed by more defines.
Is there a better way?
  
If you want to use XyWrite for databaselike operations, I'd suggest
using some sort of markup to label your fields. I work with SGML text
files, and the tagging allows me to use XyWrite to find an individual
record (short article) that starts with "A" without knowing which of the
11 A files the record is located in and to run databaselike operations
(find all articles that are biographies, and list their titles or copy
the entire text). I've used XyWrite to massage databases and
databaselike tables and almost always add markup to avoid counting
commas and diminish the likelihood that I'll work on the wrong field.
Something like this, with  as a field separator and two as record
separators:

If the field can contain a , I use a closing tag () to mark
the end of the field. It's easy enough to add the tags when setting up
the "database" using a CSV file or strip them out to export a CSV file.

Why reinvent the wheel. This is something that Notabene should be
able to do for you, out of the box. The Ibidem-Plus module allows
you to set up a structured database, search it quickly, index it on
any field you desire, and to design your own reports, including
export to CSV. Ibidem-Plus is part of the regular Notabene package.
So is Orbis, which quickly and efficiently indexes and allows
searches in HUGE quantities of text.

In my case, databasing the stuff I have to work with would, at best, add
an extra step or two, and not come with any advantages, as far as I can
tell, but that's due to the nature of my work and the files I have to
work with. A fancy XML editor (a different option) would speed up
generating the few reports I need, but would slow down and complicate
the everyday work process immensely. I no doubt could do what I do in
Notabene's editor, and considered that at one point and played with, but
I'm happy in Linux.
