Re: Strange SA/NV behavior--BK is culprit

So, the program saves a second copy of the file with a .BAK extension?
That's a workaround. It would be even better, IMO, if it saved all
.BAK files to a single directory.
What I do in my personal Save command is to make a second copy of
the file -- with an intact filename, not mangled with the .BAK
extension -- in a dedicated backup directory. Here's a U2 routine
that makes the backup copy in the  temp file directory. Of
course, it can be modified to make the backup in any directory. This
works around all the bugs and limitations you mention, including
BK=1. It handles Untitled files, too.
I wrote SA.PM because I wanted BAKs in a bk=0 environment -- as I worked
in Dosemu in Linux, I realized that bk=0 plus a SA.PM would be better
than using bk=1 because of a number of issues with XY4's "SA plus bk=1."
SA.PM's limitations aren't really issues for me, though they might be
for someone else. When SA.PM chokes on an untitled file, that's usually
fine -- I need to name something before I save it; I have had occasional
data loss, but I'm much more likely to lose data by aborting an existing
file I've modified. I have multiple files with the same name, in
different directories, so forcing backups to one directory could
eradicate other backups -- in other circumstances this would be an
excellent approach. And the BAK extension isn't a significant issue,
since my file extensions are fairly uniform, and when they are not, the
filenames are often pretty unique. there is indeed clutter at times, but
then you haven't seen my office.

FWIW, my workaround --
