1.$ SHOW DEFAULT
        DISK1:[ALAMO]
      $ SET DEFAULT DISK5:[SKONETSKI.SOURCES]
      $ SHOW DEFAULT
        DISK5:[SKONETSKI.SOURCES]

      The SHOW DEFAULT command in this example displays the current
      default device and directory names. The SET DEFAULT command
      changes these defaults, and the next SHOW DEFAULT command
      displays the new default device and directory.

    2.$ SET DEFAULT NOSUCH:[NOWAY]
      $ SHOW DEFAULT
       NOSUCH:[NOWAY]
       %DCL-I-INVDEF, NOSUCH:[NOWAY] does not exist

      In this example, the default has been set to a nonexistent
      device and directory. An error message is displayed.

    3.$ DEFINE/TRANSLATION_ATTRIBUTES=CONCEALED XYZ WORK:[INVOICES.]
      $ SET DEFAULT XYZ:[HESHELMAN]
      $ SHOW DEFAULT
      XYZ:[HESHELMAN]

      In this example, a logical name, XYZ, is defined to represent
      WORK:[INVOICES]. The /TRANSLATION_ATTRIBUTES=CONCEALED
      qualifier tells the system not to display the translation of
      XYZ in file specifications. Thus, the SHOW DEFAULT command
      displays the logical name XYZ and not its translation.

    4.$ SET DEFAULT WRK:[SCHENKENBERGER]
      $ SHOW DEFAULT
       WRK:[SCHENKENBERGER]
      $ DEFINE KUDOS WRK:[SCHENKENBERGER.TEMP1],WRK:[SCHENKENBERGER.TEMP2]
      $ SET DEFAULT KUDOS
      $ SHOW DEFAULT
       KUDOS:[SCHENKENBERGER]

      In this example, the logical name KUDOS is defined as a search
      list containing the directories [SCHENKENBERGER.TEMP1] and
      [SCHENKENBERGER.TEMP2] on device WRK. The SET DEFAULT command
      equates this search list logical name with the logical name
      SYS$DISK. The subsequent SHOW DEFAULT command displays the
      search list logical name along with its equivalence strings.

      Because the directory field has not been explicitly specified,
      the original [SCHENKENBERGER] directory remains in effect as
      the current default directory; however, unless the current
      default directory syntax ([]) is explicitly used, all file
      references are to those directories contained in the search
      list.
