EDIT VS Recovery File When EDIT VS is running, it keeps a special file named:
$volname.subvolname.ZZVSnnn
in your current subvolume. This recovery file supports the SF14

procedures outlined in the following paragraphs. When EDIT exits
normally, it deletes this recovery file. So, you only see this recovery file in
your subvolume when:
EDIT VS terminates abnormally
You do a ?FILES command from EDIT after you use EDIT VS
Some EDIT VS error messages (listed in Appendix D) tell you which
recovery file to use in the recovery procedure. For example, the following
error message tells you to use the recovery file named ZZVS992 in the
recovery procedure:

** LINES 149.11 TO 210 FOR EDIT-FILE $WORK.FICTION.STUFF
SAVED IN VS RECOVERY FILE $WORK.FICTION.ZZVS992.
