EDT saves all input from the terminal during an editing session in a
file called the journal file.   The journal file is deleted when you
exit the editor with an EXIT or QUIT command (without the /SAVE option).
If the editor is left involuntarily, the journal file is saved.

The journal file can be used to redo all the operations of an editing
session. The edited file is thereby recreated.  Type the same command
line used previously with the addition of the /RECOVER qualifier.  All
input files used in the original session must be available under the
same names as when they were first read.

Unless explicitly overridden by the /JOURNAL qualifier on the command
line, the journal file will have the same name as the output file,
except that the file type will be JOU and the file will be written in
the current default directory.
