TEMPDIR   -- create directory for temporary files

      If you need large amounts of file  space while you are logged in but
   don't need to keep the files between terminal sessions,  you can create
   files  in a  temporary  directory for  the  duration  of your  terminal
   session.    You can  invoke PUBLIC:TEMPDIR.COM  to  create a  temporary
   directory which you  can address with the logical  name SYS$SCRATCH (or
   TEMP,  since SYS$SCRATCH is a bit long).   Files in this directory will
   be deleted when  you log off.   To  refer to a file  in this directory,
   prefix the  file name with SYS$SCRATCH:    (or TEMP:).   To  create the
   directory and define TEMP, enter the command

                  $ @PUBLIC:TEMPDIR  TEMP

      Note that all files in this temporary directory are deleted when you
   log off.   If you want to save any of the files,  you must copy them to
   your regular  directory.   If  you are  disconnected during  a terminal
   session,  you will probably lose your  temporary files.   If the system
   goes down, the files may still be there when you log back in, but don't
   count on it.    It is probably unwise to use  the SYS$SCRATCH directory
   for any files that are not truly temporary.

          FUNCTION                   COMMAND

          Create directory and       @PUBLIC:TEMPDIR  TEMP
            define TEMP
          Copy file X.DAT to TEMP    COPY   X.DAT   TEMP:X.DAT
          List TEMP directory        DIR    TEMP
          Delete X.DAT from TEMP     DELETE TEMP:X.DAT;
          Create file with EDT	     EDIT   TEMP:X.DAT
          Copy file from TEMP        COPY   TEMP:X.DAT  X.DAT
            to default directory
          Set default to TEMP        SET DEFAULT  TEMP
          Set default to your        SET DEFAULT  SYS$LOGIN
            directory

   NOTE: At this time, we do not currently delete the temporary directory when
         the user logs off.
