Documentation
How much prompting to do when saving articles.
If it is nil, no prompting will be done, and the articles will be
saved to the default files. If this variable is always, each and
every article that is saved will be preceded by a prompt, even when
saving large batches of articles. If this variable is neither nil not
always, there the user will be prompted once for a file name for
each invocation of the saving commands.
Probably introduced at or before Emacs version 19.32.
