          SETDEF.COM is a very useful command file for quickly changing the
     default directory.  It provides many options which will allow:

     1.  Showing the current default directory ("@setdef ")

     2.  Changing to a subdirectory of current directory
         ("@setdef >subdir")

     3.  Changing to SYS$LOGIN directory ("@setdef ;")

     4.  Changing to a subdirectory of SYS$LOGIN directory
         ("@setdef ;subdir")

     5.  Changing to the next highest directory ("@setdef <")

     6.  Changing to top level of current default ("@setdef .")

     7.  Changing to subdirectory of the top level current default
         ("@setdef .subdir")

     8.  Changing default to specified directory, where directory given may
         be a logical name ("@setdef herdir")

     9.  Saving current default in logical name sd$default ("@setdef (")

    10.  Restoring default from logical name sd$default ("@setdef )")

    11.  Showing subdirectories of current default ("@setdef >")

    12.  Typing help for SETDEF.COM ("@setdef ?")


          By defining the symbol "SD" to execute SETDEF.COM (i.e.  SD :==
     @SETDEF) all commands can be shortened even futher.
