JOURNAL_OPEN

     Opens a journal file and starts recording the keystrokes of the editing
     session.  The journal file remains open until you end the editing
     session or use JOURNAL_CLOSE.  You use a journal file to recover your
     edits in case an editing session is interrupted by a system failure
     (such as a break in communications between your terminal and the
     computer).  For more information, see DCL HELP on EDIT/TPU /JOURNAL and
     /RECOVER.

  Syntax

     [string2 :=] JOURNAL_OPEN (string1)

  Parameters

     string1    The file specification for the journal file to be created
                for the editing session.  If you do not specify a device (or
                disk) and directory, DECTPU uses the current (default)
                device and directory.  The default file type is .TJL.

  Example

     JOURNAL_OPEN ("test.jou");

     Opens a file called TEST.JOU in your your current, default directory,
     as the journal file for the editing session.
