1 DEFAULT

	DEF is a foriegn command which allows one to change ones default
 directory in a simpler fashion than using the SET DEFAULT command.  
 At the same time, if one has allowed privileges, and if SETUIC is on the
 system and defined as a foreign commmand, one's current UIC is changed to
 the UIC of the target device/directory.   To change ones directory type

		DEF  directory_name

 Typing just  DEF .sub_directory   will switch you to 

		[directory_name.sub_directory].

 Typing just DEF [-]  or DEF \ will back you up one level toward the
 root directory.
 
 	DEF takes a more general syntax in that it also will accept
 both devices and directories. ie

		DEF  DEV:DIRECTORY

 If the device is specified, the ':' must seperate it from the directory
 with no intervening spaces.  The [ and ] are optional.
 
   DEF has two special symbols "." and "$".  DEF $ will move you back to
 your login directory while DEF . will move you to the last directory you
 were on. DEF maintains a symbol LAST_DEFAULT for each user which contains
 the last directory for which DEF was used to move to.  The symbol "&" takes
 you to the root of the current directory tree.  The percent sign "-" followed
 by a number from 1 to 8 takes you to that number of last directories, e.g.
 suppose you visit the following directories in order:

    [AAA]
    [BBB]
    [CCC]
    [DDD]

 The command DEF -2 will take you to [AAA] (since the current is [DDD], the last
 was [CCC] and the first before that is [BBB], or -1).  To see the numeric values,
 and also get brief help on the command, use the "?" arguement.

 If you try to specify a directory or device which does not exist, DEF will
 issue a warning message and not execute the command.

2 SUPER_DEF

 DEF can be defined with additional features:

    1) Prompt: Change the DCL prompt to reflect the current node.
       
       A full explanation is available under HELP SET_PROMPT
       but for quick usage, include the following in your LOGIN.COM:

    $DEFINE/NOLOG KMS_PROMPT_DESCRIPTION "REVERSE|NODE=[!]|DIR|PROMPT=>|NORMAL"

    2) DEF @: Show previous directories.

       This shows the previous directories 

 To have this feature, you must do the following in your LOGIN.COM file or
 from DCL each time you log in:

    $RUN SYS$UTILITY:SET_PROMPT 
    $DEF :== @SYS$COMFILE:DEF
