   1.$ WRITE SYS$OUTPUT F$UNIQUE()
     414853555241159711D7DF797CCF573F
     $
     $ WRITE SYS$OUTPUT F$UNIQUE()
     414853555241509811D7DF797E3F2777
     $

     This example shows how a unique string is returned on
     subsequent WRITE commands.

   2.$ OPEN/WRITE TEMP_FILE 'F$UNIQUE()
     $ DIRECTORY

     Directory WORK1:[TEST]

     594B53554C421C9C11D75463D61F58B7.DAT;1

     Total of 1 file.
     $
     $ CLOSE/DISPOSITION=DELETE TEMP_FILE
     $ DIRECTORY
     %DIRECT-W-NOFILES, no files found
     $

     The first command creates a temporary file and gives it a
     unique name, which is displayed by the subsequent DIRECTORY
     command. After the file is later closed and deleted, it no
     longer shows up in the directory.
