Any of the WordStar versions will handle file sizes limited by disk space
only.  (WordStar 4.0 includes some nifty program editing features even,
like variable tab widths and autoindent.)

Here's a little known tip:

There are actually two WordStar temporary files.  Your original file
is only read from, and becomes the .BAK file.  As you move forward
through the file buffer spills become a temporary file that grows
as you cursor forward -- and this file becomes the new file.  If you
make changes early in your file, move forward, then move backward,
another temporary file is created (called EDBACKUP.$$$ in ws 3.3).
So the nominal space required on your disk for editing a file with
WordStar is free space equal to or greater than twice the size of your
original file.

However, if you don't back up through the file, the BACKUP temp file
isn't needed, and you can edit a large file using only as much free
space as the size of your original file.
